Someone who dedicates their life to hunting down ex-Nazis, or is dedicated to hunting down one particular Nazi because of what they did in World War II (note: this trope doesn't apply just because the antagonist happens to be an ex-Nazi, it's only for someone who hunts them regularly). Often a Badass Israeli who might be working for Mossad, a result of the high-profile kidnapping of Adolf Eichmann from Argentina in 1960. In reality, Mossad stopped chasing war criminals not long after this event, as more urgent threats to Israel took priority (for example, hostile neighboring Arab regimes are considered bigger threats to Israel than old Nazi war criminals).
Expect the former Nazi to be living somewhere in South America in his well-guarded mansion financed by Nazi Gold, from which he plots the return of the Third Reich. Hardly Truth in Television, as genuine war criminals go to some trouble to avoid drawing attention to themselves. And this usually involves living modestly and often working in low end jobs such as manual labor. And as far as all that Nazi Gold, there are some other more plausible theories about where it ended up.
Something of a Discredited Trope these days, as anyone who served in World War II gets too long in the tooth to be anything other than a Nazi Grandpa. And the generation that would have been old enough to be movers and shakers in the Nazi party would now be centenarians. Finally, the end of the Cold War dramatically expanded the choice of stock villains.
However, there are Neo-Nazi hunters in Real Life, who are dedicated to making life Hell for anyone they suspect of being a Neo-Nazi or sympathizer; many of these are affiliated with the Punk Rock music scene. Groups and movements such as Anti-Fascist Action and Skinheads Against Racial Prejudice are a prominent example of this type of modern-day Nazi Hunter.
Very common in Nazisploitation films.
- In the Marvel Universe, Silver Sable's father did this, with the Wild Pack originally being established as a Nazi hunting group.
- National Lampoon: There was an extended comic story about "Gunnar Von Weissen", an ex-Nazi who hunted former concentration camp prisoners, a la Wiesenthal.
- There is an indie comic called Manimal (no, not that one) about a Super Hero who tracks down and slays the Nazis responsible for turning him into a freak. This comic was reviewed by The Cinema Snob and Linkara.
- Hellboy occasionally tracked down Nazis after the war. Some of these Nazis are still around and he expresses his disgust of Nazis every time he sees them.
- Captain America himself continues to do this to this day, thanks to the Red Skull being very hard to kill.
- Much like Cap, Atomic Robo also continues to fight Nazi super-science, by virtue of Helsingard having god knows how many hidden labs throughout the world. Robo also found Otto Skorzeny living in Madrid in 1974, but Skorzeny had actually brought him there so that he could goad Robo into killing him, to free him from the pain of his terminal cancer. Robo declined.
- Rebecca's sister Sarah in Requiem Vampire Knight. She kills Otto (an old Nazi hiding in Argentina at that point) in revenge for killing Rebecca in a concentration camp, sending him to Resurrection.
- In the '80s, Magneto joined the ranks of several Marvel villains in the Acts of Vengeance Crossover simply so that he could get close to the Red Skull and bury him alive. Magneto was a Holocaust survivor so there was no love lost between him and the Skull.
- The Sin City short story Rats features an elderly Nazi war criminal, apparently living in secret in America. A mysterious Nazi Hunter soon kicks in the door and kills him by shoving him in the oven. It is speculated that the Nazi Hunter in this story is a young Mob Boss Wallenquist, a German mafia leader.
- A back-up story in an issue of Savage Dragon involved the Super Patriot tracking down a cult of ninja cyborg Nazis. Since he was a WWII vet, he took great pleasure in blowing them apart.
- Subverted in the movie The Statement (from the novel by Brian Moore). An old Vichy French war criminal played by Michael Caine kills an apparent Nazi hunter in self-defence, but when the police start investigating it turns out that the Nazi hunter was just a hitman with a fake Jewish-Canadian background, hired by a couple of influential war criminals who wanted to get rid of Caine as he knew too much about them.
- Erik spends the first twenty minutes or so of his screentime in X-Men: First Class tracking down and killing Nazis. In fact, his reason for joining the X-Men is so that he can find and kill Sebastian Shaw, the mutant Nazi who killed his mother.

- Inglourious Basterds features a squad of JEWISH-AMERICAN-SOLDIERS! killin' Nazi officials and soldiers during WW2 as opposed to after it. One of their member also happens to be a former German soldier that developed a taste for killing Nazis himself after he was subject to torture by Gestapo agents.
- SLC Punk! has a modern take on this; the main characters find Neo-Nazi punks and beat them up. This is mostly due to the Neo-Nazis calling themselves punks rather than any moral reasons.
- The Debt follows three young Mossad agents attempting to kidnap a Captain Ersatz version of Dr. Mengele from East Berlin in the 60's.
- In the French movie (and remake) Marie-Octobre, the target is not the former Nazi himself, who was simply an enemy soldier: the problem is that said German revealed the presence of a traitor in the former resistance movement.

- The Australian short film Ubermensch (based on a story by Kim Newman) has an aging Nazi hunter visiting his last target in his cell in an American prison... who's still as young as the day they first met. Turns out this is an alternate Superman who landed in Nazi Germany instead of the United States. So how do you kill a man with superpowers who's effectively immortal?
- The Odessa File by Frederick Forsyth has Simon Wiesenthal as a cameo character. The protagonist is an Intrepid Reporter tracking down a German war criminal. However his motives are revealed to be entirely personal.
- The Boys from Brazil by Ira Levin. The protagonist is an obvious Wiesenthal expy.
- Subverted in Cobra by Andrew Vachss. Burke motivates The Mole (who's Jewish) by saying the people he's chasing are Nazis, when the only Nazis he knows are pathetic wannabes to whom he sells copies of Hitler's final speech (actually Simon Wiesenthal addressing a crowd of Holocaust victims).
- Recycled In Space in The Hand of Thrawn, a Star Wars Legends duology whose conflict is set off by the discovery of the Caamas Document, which details how a group of Bothan collaborators helped the Galactic Empire glass the planet Caamas, an act of genocide against its pacifist anti-Empire inhabitants. This sparks a near-Civil War in the New Republic, with some members trying to hold the entire Bothan species accountable since the section naming the collaborators is conveniently missing,note and many of the protagonists go to great lengths to find an intact copy. Luke Skywalker and Mara Jade ultimately find an intact copy in Grand Admiral Thrawn's archives in the Unknown Regions, and the surviving collaborators are quickly brought to justice.
- Kessler, the sequel to Secret Army, in which the title character is pursued by a German police officer, and a young Israeli woman seeking revenge for her roommate being killed by neo-Nazi thugs.

- Sue Sylvester's mother Doris on Glee.
- The man Sister Jude goes to for information on her co-worker, Nazi scientist Dr. Arden, also known as Hans Gruper in American Horror Story: Asylum. This takes place in the 1960s, so there are likely a good many Nazis still running around.
- In Search of... covered the international hunt for Josef Mengele, basing their "facts" on the allegations of Simon Wiesenthal (see Real Life). Unfortunately now that Mengele's identity while living in South America is known, the dramatic tales of his narrow escapes from nazi hunters have turned out to be bogus.
- The Trope Codifier is BJ Blazkowicz from Wolfenstein, he dedicated his entire life to hunt down Nazis over and over again, he first took down Hitler himself in Wolfenstein 3D, and later on dealt with supernatural Nazis. BJ is rather picky on his foes, he only hunts Nazis.
- The Soldier from Team Fortress 2... sort of. He traveled to Poland during the war to kill Nazis and didn't stop until four years after the war was over, because he didn't realize the war was over. What form this Nazi-killing spree took, exactly, is not made clear, but it's heavily implied that they weren't actually Nazis.
- The New California Republic from the Fallout series becomes this towards the Enclave after the latter's defeat at the hands of the Chosen One. The two eventually go to war with each other and despite numerous casualties on both sides, the NCR prevailed and the Enclave was forced to relocate to the East Coast to lick their wounds and bide their time; those who stayed behind were executed on the spot, ostracized, or successfully integrated into the NCR to avoid further persecution. In one particular character's ending in Fallout: New Vegas, after the conclusion of the Second Battle of Hoover Dam, his connections and history with the Enclave soon were revealed by both the NCR and the Brotherhood of Steel, and the two factions team up together to hunt him down and attempt to try him for his affiliations with the organization, who had a rack sheet of crimes against humanity and non-humanity alike.
- Sniper Elite V2, Sniper Elite III, and Sniper Elite feature Lt. Karl Fairburne, whose missions mainly involve sabotaging Nazi wonder-weapons projects before they can be completed. Often, as part of his missions, he's also tasked with hunting the Nazi scientists and officers behind the projects in order to achieve No Plans, No Prototype, No Backup.
- Simon Wiesenthal
- The Simon Wiesenthal Center has recently started to realize that Nazi war criminals are soon going to be all dead, so they've redirected toward hate groups, and toward anybody accused of antisemitism, except, oddly, Argentine dictators who openly praised Adolf Hitler.
- Ingrid Rimland once cooperated with Simon Wiesenthal to hunt Josef Mengele, even writing a book, Demon Doctor, about that hunt. Later, she'd meet Holocaust denier Ernst Zündel, marry him and is today a Holocaust denier herself.
