Cadillacs and Dinosaurs is an animated television series produced by De Souza Productions, Galaxy Films and Nelvana, which aired on CBS as part of its Saturday morning children's lineup in the United States from 1993 to 1994, lasting for one season of 13 episodes.

The series chronicles the exploits of Jack Tenrec and his crew of ecological freedom fighters known as the "Mechanics".

Jack Tenrec's often-reluctant companion is Hannah Dundee, an ambassador from Wasoon somewhere south, a place technologically much further behind than the City in the Sea.

Dundee hires Tenrec as a liaison, while she attempts to create clear communication between her land and the modern civilization.
