A Day in the Life of Ranger Smith is a stand-alone animated television special, and a parody of a Hanna-Barbera cartoon series, The Yogi Bear Show, which revolves around Ranger Smith. A Day in the Life of Ranger Smith was made by The Ren & Stimpy Show creator John Kricfalusi and his company Spümcø. A Day in the Life of Ranger Smith originally aired on Cartoon Network on September 24, 1999, along with Boo Boo Runs Wild, a similar Yogi Bear-themed stand alone special.

Since its original debut in 1999, A Day in the Life of Ranger Smith has aired on Cartoon Network's late night programming block, Adult Swim. The special was jokingly dedicated to William Hanna and Joseph Barbera, despite the two of them still being alive at that time.

This marked the last Yogi Bear production in which Greg Burson voiced Yogi. Stephen Worth replaced Burson for Boo Boo Runs Wild and Burson never voiced the character again; he was arrested in 2004 (effectively ending his career) and died in 2008.
