Robert Smigel (born February 7, 1960) is an American actor, comedian, writer, director, producer, and puppeteer, known for his Saturday Night Live "TV Funhouse" cartoon shorts and as the puppeteer and voice behind Triumph the Insult Comic Dog. He also co-wrote the first two Hotel Transylvania films, You Don't Mess with the Zohan, and Leo, all starring Adam Sandler.

Robert Smigel was born in New York City, to Lucia and Irwin Smigel, an aesthetic dentist, innovator and philanthropist. He is Jewish and frequently went to Jewish summer camp. He attended Cornell University, studying pre-dental, and graduated from New York University's College of Arts and Science in 1983 with a degree in political science.

Smigel began developing his comedic talent at The Players Workshop in Chicago, where he studied improvisation with Josephine Forsberg. Bob Odenkirk was a fellow student there. Smigel was also a member of the Chicago comedy troupe "All You Can Eat" in the early 1980s.

Smigel first established himself as a writer on Saturday Night Live by joining the writing staff when Lorne Michaels returned as executive producer for the 1985–1986 season. Smigel was hired after then-SNL producers Al Franken and Tom Davis saw Smigel in a Chicago sketch show. Smigel was among the few writers who survived a purge of writers and cast at the conclusion of the "disappointing" 1985–1986 season. This is when Smigel began to write more memorable sketches, including one where host William Shatner urged worshipful attendees at a Star Trek convention to "get a life." Smigel rarely appeared on screen, though he was credited as a featured player in the early 1990s and played a recurring character in the Bill Swerski's Superfans sketches.

While on a writers' strike from Saturday Night Live following the 1987–88 season, Smigel wrote for an improvisational comedy revue in Chicago with fellow SNL writers Bob Odenkirk and Conan O'Brien called Happy Happy Good Show.

Smigel co-wrote Lookwell with Conan O'Brien for NBC. The pilot never went to series, but it has become a cult hit and has screened live at "The Other Network", a festival of un-aired TV pilots produced by Un-Cabaret, featuring live and taped intros by Smigel. Smigel later became the first head writer at Late Night with Conan O'Brien, where he created numerous successful comedy bits, including one where Smigel performed only the lips of public figures which were superimposed on photos of the actual people. (This technique was pioneered on the Clutch Cargo cartoon series as a cost-saving measure, and was known as Syncro-Vox.)

In 1996, Smigel wrote and performed on the short-lived Dana Carvey Show, a primetime sketch comedy program on ABC. Despite its premature end, the show provided Smigel the opportunity to debut his first cartoon The Ambiguously Gay Duo. Upon the show's cancellation, Smigel continued developing more cartoon ideas the following summer and would begin airing them on Saturday Night Live under the TV Funhouse banner. Smigel would later claim "My whole career came out of the impulse to do cartoons on The Dana Carvey Show."

Smigel's most famous creation, however, would be the foul-mouthed puppet Triumph the Insult Comic Dog, who mercilessly mocks celebrities and others in the style of a Borscht Belt comedian. This character debuted on Late Night with Conan O'Brien in February 1997 and would continue to make appearances on the show, as well as others, for many years to come.
