''Tsuribaka Nisshi'' (釣りバカ日誌 ''Fishing Fool's Diary'') is a fishing {{manga}} by Jūzō Yamasaki (story) and Kenichi Kitami (art) that has been serialized in ''Big Comic Original'' since 1979. It won the 28th Shogakukan Manga Award in 1983. The series has been adapted into a popular and long-running movie series, as well as a TV {{anime}}.

The story focuses on salaryman Densuke Hamasaki (a.k.a Hama-chan), whom his supervisor, Sasaki, has dubbed the "Fishing Baka" because of his passion for fishing. One day, Hama-chan meets and befriends an older fisherman named Su-san, who turns out to be Ichinosuke Suzuki, the CEO of the "Suzuki Construction" company that employs Hama-chan. The stories tend to focus on their relationship inside and outside the office.

!!The manga offers examples of following tropes:

* BenevolentBoss: Su-san. {{Foil}} for Sasaki.
* {{Crossover}}: With ''Series/BakuryuuSentaiAbaranger'', of all things: During the time the short-lived anime adaptation was on TV, one [[MonsterOfTheWeek Trinoid]] kidnapped Hama-chan's son Koitarou in an episode of ''Abaranger''. Hama-chan even went from his anime world into the real world to help the Abarangers, using his fishing pole to rescue the victims who were transformed into olives. Yeah, one should apply the MST3KMantra.
* PrintLongRunners: Ongoing since 1979.
* {{Salaryman}}: Hama-chan, and he seems to be thinking about fishing all the times, even at work.
* {{Seinen}}: The content is not really mature, but fishing is rather a hobby for adult men.
* SliceOfLife
