Kevin Jeffrey Clash is an American puppeteer, director and producer best known for puppeteering Elmo on Sesame Street from 1985 to 2012. He also performed puppets for Labyrinth, Dinosaurs, Oobi, and various Muppet productions.

Elmo is a red Muppet character on the children's television show Sesame Street. A furry red monster who speaks in a high-pitched falsetto voice and frequently refers to himself in the third person, he hosts the last full five-minute segment on Sesame Street, "Elmo's World", which is aimed at toddlers. He was most often puppeteered by Kevin Clash, but since Clash's resignation in late 2012, Elmo has been puppeteered by Ryan Dillon.
