Kenny voices many characters in many productions, and in his own words "a lot of sweet, kind of stupid yellow characters for some reason" (which would explain Heffer, Dog, and SpongeBob). When he doesn't play those, Kenny usually plays comically serious, authoritative types (usually doctors, businessmen, and game show hosts).
Kenny played his first set of voice actor roles for Rocko's Modern Life. Joe Murray auditioned Kenny for voice acting roles for the series in a large casting call in Los Angeles, California, United States. On one occasion during the production, the producers required Kenny to fill the role of Charlie Adler, who was absent on that occasion. In addition, Kenny had to perform one song and learn how to play another song within ten minutes due to time constraints. Kenny achieved this goal. He said that this helped him believe that he could stand "toe to toe" with other voice actors.
Joe Murray chose Kenny for a voice acting position in Camp Lazlo because Murray, after seeing Kenny's previous work for Rocko's Modern Life, felt that Kenny "adds writing to his roles" and "brings so much".
He's been the announcer for Nickelodeon's annual Kids' Choice Awards for years; at the 2007 show he called himself the "Man of 1,000 Voices, all of them this one." He was featured as the Voice in a Box at the 2008 show, and at the 2009 show he claimed to be the only announcer who does all of his own stunts.
He and his wife, Jill Talley, played the couple in the music video for The Smashing Pumpkins' "Tonight Tonight".
Starting in season 9B, Kenny became the voice director of SpongeBob.
Has a Twitter, which he very rarely uses — once a year, in fact, to tweet that he is still not tweeting.

Tropes associated with Tom Kenny:
- Bleached Underpants: According to his interview with Marc Maron, the origin of his most famous voice, SpongeBob, was a ticked off, swearing little person who was auditioning for an elf in a Christmas commercial. Apparently Nickelodeon does not like him telling that story.
- The Cameo: Appeared along with wife, Jill Talley, in the movie Sky High (2005).
- Childhood Friends: With Bobcat Goldthwait. The two of them were originally part of a comedy duo known as Tomcat and Bobcat.
- Cloudcuckoolander: Frequently plays these.
- Disney Owns This Trope: Nickelodeon currently owns the rights to his SpongeBob voice, meaning he's not allowed to use it for any other role.
- Large Ham: The characters he voices are inclined to be theatrically comedic in an over-the-top manner. The delivery of Tom's voice reinforces this.
- Man of a Thousand Voices: He has a very large Western Animation discography consisting of voice roles in recognizable cartoons typically produced by Cartoon Network, Nickelodeon, and Disney.
- Monster Clown: As Binky the clown in Shakes the Clown.
- Playing Against Type: As Fixit, Doctor Octopus, Nute Gunray and the Anti-Monitor.
- As a loud, obnoxious children's show host with reality-warping powers (and the voice of his rabbit sidekick, Loomis) on The Haunting Hour episode, "Uncle Howee" in one of the few times Tom Kenny has done work on a live-action show that wasn't a sketch comedy show, like The Edge and Mr. Show or a behind-the-scenes documentary where viewers get to see the men and women behind the voices of their favorite cartoon characters [i.e., I Know That Voice].
- Played with a bit in Adventure Time. At first the Ice King seems like another one of his humorous roles, but then came The Reveal of Ice King's past which showed that he was once an ordinary guy by the name of Simon Petrikov, and he seems to be quite serious.
- Woody Johnson on Brickleberry. While it is true that Tom Kenny has played a Fat Bastard (Heffer Wolfe from Rocko's Modern Life), it was Played for Laughs and Heffer being a bastard is more due to social ignorance than being a sociopath. Not the case with Woody Johnson. On top of that, the voice Tom Kenny uses for Woody Johnson doesn't sound like any character he's played before.
- And then there's the child rapist Mr. Jellybean on Rick and Morty.
- One of his earliest (not to mention only live-action) roles was as the evil, murderous Binky in Shakes the Clown. Could also count as Early Installment Weirdness.
- He was also the Sharper Image Chair in Eight Crazy Nights.
- Real-Life Relative: He and his real-life wife, Jill Talley, have worked together numerous times.
- Relationship Voice Actor: Has worked alongside Grey DeLisle, Tara Strong, Carlos Alazraqui, Charlie Adler, Bill Fagerbakke and many others.
- Star-Making Role: He was a complete unknown when cast for Rocko's Modern Life. SpongeBob SquarePants pushed his fame further.
- Talking to Himself: In several series.
- What Could Have Been:
- Kenny was in the running to host Double Dare 2000 but Jason Harris eventually got the job.
- In the early 90s, he was in the running to be on Saturday Night Live, going as far as to audition to Lorine Michaels himself. However, there were only two spots available at the time, and they wound up going to David Spade and Rob Schneider.
