Time for Timer is a series of seven short public service announcements broadcast on Saturday mornings on the ABC television network starting in 1975. The animated spots feature Timer, a tiny cartoon character who is an anthropomorphic circadian rhythm, the self-proclaimed "keeper of body time." The series was produced by the cartoon studio DePatie-Freleng Enterprises.

Timer first appears in the 1973 ABC Afterschool Special "The Incredible, Indelible, Magical, Physical Mystery Trip", where he was voiced by Len Maxwell. In this special, he works inside the body of a man named Uncle Carl.

Timer also appears in the 1974 ABC Afterschool Special "The Magical Mystery Trip Through Little Red's Head", working inside a teenaged Red Riding Hood. In this special, and in all future appearances, Timer's voice was provided by actor Lennie Weinrib.

Time for Timer ran until 1992 concurrently with ABC's other educational spots, primarily The Bod Squad and Schoolhouse Rock! They generally appeared during cartoon programs at the end of commercial breaks. The shorts included a Consultant credit for Dr. Roslyn B. Alfin-Slater, UCLA School of Public Health.
