Monterey Jack is a type of cheddar-style cheese first made in California using pasteurized cows’ milk. It is commonly sold by itself, or mixed with Colby cheese to make a marbled cheese known as Colby-Jack (or Co-Jack).

An aged version of this cheese, known as Dry Jack, can be grated and used much like Parmesan cheese.

Monterey Jack is one of the central characters in the animated television series Chip 'n Dale Rescue Rangers. He is a cheese-obsessed mouse.
