An early episode of Adam-12 saw Malloy and Reed approach every white 1958 Ford convertible with trepidation ... since a stolen boa constrictor might be hidden in the trunk of one of them.
Subverted with Agent Scully on The X-Files. In "One Breath", her mother tells a story how she felt guilty for shooting a snake with her new BB gun. Although deathly afraid of snakes, she held the snake and it died in her hands, which is very weird as people with this phobia are grossed out with only pictures of snakes. When Mulder and Scully investigate cases involving snakes, she isn't exactly on edge ("Die Hand die Verletzt") and she even gets a tattoo of a snake eating its own tail in "Never Again". On the other hand, there are lots of snakes in "Signs and Wonders", but even Mulder who doesn't suffer from this phobia is very nervous around them.
On an episode of The Cosby Show, Rudy freaked out after seeing a small garter snake in the basement. Clair told her to calm down, saying she and Cliff would take care of it... Then, once she and Cliff were alone, she freaked out even more than Rudy had, and was on edge the entire episode. (At the end, when they caught it, Rudy actually thought it was "cute".)

Grant Imahara is also arachnophobic. And he gets the same type of "treatment" that Adam got...
Shane the Red Ranger from Power Rangers Ninja Storm. First mentioned by Tori to prove it's really her and not her evil clone, it turns up later in a surprisingly subtle fashion - a flashback of kid-Shane rescuing an alien ball of light from a spider-web.
Chief O'Brien once admitted to a fear of spiders in an episode of Star Trek: The Next Generation. He not only got over it in time, he actually kept a pet tarantula. Presumably Keiko told him to leave it behind when they moved to Deep Space Nine.
Hank from Sirens US is afraid of spiders. He kept it a secret for years, because he knew that Johnny would give him shit over it. And indeed, as soon as Johnny found out, he proceeded to give him shit.
Niles Crane from Frasier has a very severe form of this. He often believes that insects are bigger than they are, he has carried a ridiculous amount of bug repellent with him on more than one occasion, and, while Frasier insists that he should see a therapist, he never does.note This is related to his larger fear of dirt and compulsive cleanliness.

One witch asks her if she'd like to "play with some rodents" and proceeds to put a bucket of rats into the cage with the girl, who happens to be terrified of rats. The girl then freaks out and says: "Why did it have to be rats?!"
The Brady Bunch: Alice is revealed to be afraid of mice in "The Impractical Joker" after seeing a small, white mouse running loose in the house. The mouse was on loan to high school freshman Greg for a science project, and Jan – playing up her one-episode practical joking side – lets the mouse loose.

The warden in one episode of The Mentalist is afraid of mice/rats. What does Jane do? He uses a muffin and some other tools to catch a mouse/rat, and as part of his plan to break out of jail, essentially scares the crap out of the warden so he won't stop him.
Gary from Miranda is scared of mice, and jumps onto a chair when told there's one in Miranda's flat.

Mr Smoketoomuch in Monty Python's Flying Circus gained his odd speech impediment (pronouncing the letter "C" as "B") after being attacked by a Siamese bat. No, not a cat — a Siamese bat (they're more dangerous).
Rei Tachibana/Dyna Pink from Kagaku Sentai Dynaman. The mere sight of cat just freaks her out and she's rendered mostly incapable of fighting a cat monster, and it gets worse when said cat monster just transform the Mooks into cat statues. Ironically, she wants to develop a tool to communicate with animals... but can't even touch a cat without freaking out.
Ed in Flashpoint, at least according to Greg. Ed claims it was just once with a "scary cat," a point which Spike (hilariously) backs up.
Anya from Buffy the Vampire Slayer. She dressed up as a bunny for Halloween ("Bunnies frighten me."), sang about bunnies in "Once More, with Feeling!", then was standing on a table when misspoken incantations had filled the Magic Box floor with rabbits of all shapes and sizes, calling it a "cotton-top hell". Somewhat justified, in that a highly traumatic incident involving an unfaithful husband, angry villagers, and rabbits was the catalyst for her becoming a demon in the first place.

Tokumei Sentai Go Busters: Hiromu (a.k.a. Red Buster) is surprisingly afraid of chickens, to the point where even seeing a picture of one causes him to freeze up. This is due to a traumatic event in his childhood where he was accidentally locked inside a chicken coop.

In the "Hammer Drop", we find out that Jamie Hyneman apparently has a mild case of acrophobia. This comes up again in the "Outtakes Special". In some unaired footage from "Plywood Builder", Jamie is trying to reassure Christine about her impending (until she decided not to) zipline ride, and says "You know I'm afraid of heights". And he jumps off a building in "Dumpster Dive" ... but you could tell he wasn't happy about it. He was even less happy about crossing a 100-foot duct tape bridge 50 feet above the ground. Though, considering how unstable the thing was...
Colleague Tory Belleci is also acrophobic, so he had to go up in a stunt plane for the "Cold Feet" myth.

This came up right before he and Sam had to crawl across a tiny strip of floor over an apparently bottomless pit. He did fine with it, and eventually threw himself off their "bridge" to save their companion, 'cause he's Daniel.
Presenter James May on Top Gear gets height vertigo (a spinning sensation when he looks down from a height). He took flying lessons and acquired a private pilot's license to help himself learn to cope with it. He's still not quite over it though, as evidenced by the Bolivia special.
Alice from Alice is very afraid of heights. Most likely to balance the fact that she is an Action Girl.
Clark Kent in the early seasons of Smallville. Insert clever one-liner about "Irony" here.

She takes an aviaphobia group therapy class conducted by Frasier on a plane to get over it. Carla overcomes her fear but Frasier suddenly becomes freaked out about being on a plane.
The first episode of The Bob Newhart Show has Bob heading a workshop for people trying to overcome their fear of flying.

Horatio Hornblower: Horatio is prone to sea-sickness and is really afraid of heights. Excellent material for an officer in the Navy, wouldn't you say? His fear of heights is referenced quite often, and he has to climb in the riggings or on the fighting top and deal with shortening sails quite a lot. In "Retribution", he volunteers himself to descend from a cliff on a rope and his pal Archie mischievously reminds him of his anxiety.
Archie Kennedy:[saucily] I remember when you used to be scared of heights, Mr Hornblower.
Horatio Hornblower:[measures the height he must descend from] Nothing's changed, Mr Kennedy.
Malcom Reed from Star Trek: Enterprise has a fear of drowning that prevented him from carrying on his family's naval tradition. Oddly enough, this fear doesn't extend to the vacuum of space. Maybe he realized that Space is NOT an ocean.
George Ikaruga from Ultraman Mebius isn't afraid of water per se (he's a good swimmer, in fact). He's specifically afraid of the Ocean. Perhaps justified in his case, as when he was younger, something horrible would happen to him every time he went there. He eventually decided the Ocean just had it in for him.
Zoe Graystone in Caprica, due to almost dying in a housefire as a child.
Doctor Who: The Doctor, at least in his third incarnation.

A.J. from The River has speluncaphobia, the fear of caves, thanks to having been in a mining accident.

Alan Shore in Boston Legal, as we learn when he has a case involving a professional clown who shows up to court in full costume. Alan avoids looking directly at the man for fear of publicly wetting himself.

(Unfortunately the mental instability caused by his condition ultimately led him to attack Sir Prince Charles at an award ceremony.)
Tommy from Big Wolf on Campus is afraid of ending up alone due to people finding out about his lycanthropy. And Merton is scared of monster movies (which is kind of weird, because he's a Goth).
Balloons (globophobia) — Lacey and Davis in an episode of Corner Gas. Also, by the end of that episode we find out that Brent seems to have a fear of globes.
Wanda's implied agoraphobia (fear of open space). It's especially ironic as she lives in Saskatchewan, which has nothing but open space.
As revealed on Attack of the Show!, co-host Olivia Munn is also afraid of balloons. Needless to say, fellow co-host Kevin Pereira takes so much delight in tormenting her whenever the subject comes up.
Embarrassment: Richard Hammond. "I have several recurring nightmares. One in which I am presenting a radio show and can't work the desk, another in which I find myself on stage with a truly catastrophic band. I am only waiting now for Top Gear to make me run naked through a shopping centre on a Saturday and I will have completed the set."

A scene on The Sketch Show has the five stars in a support group for phobias - Lee has a fear of people screaming, Jim has a fear of apologies, Karen has a fear of repetition, Ronnie has a fear of awkward silences and Tim barks at people's phobias. This combination repeatedly sets off chains of screaming.
On Crossbones, Selima is severely agoraphobic, to the point where she violently refuses to leave Blackbeard's house.
The Doctor Who story "The Robots of Death" has 'robophobia' or 'Grimwade's Syndrome' as a reasonably common psychological condition in the setting, apparently caused by people with particularly keen body language skills subconsciously associating the stiff, humanoid robots with walking corpses. Poul suffers from this condition, and in the sequel Expanded Universe material it is revealed both Toos and Uvanov have developed cases of it as a result of the trauma they suffered at the hands of the robots, while Poul's has worsened to the point of being barely functional.
