The Zoo Interchange is a freeway interchange on the west side of Milwaukee, Wisconsin. It was built in 1963, as one of the first Interstate Highway projects in Wisconsin. It forms the junction of I-94, I-894, and US-45. It is nicknamed because of its proximity to the Milwaukee County Zoological Gardens.

The design of the Zoo Interchange was considered progressive for its time, featuring ramps on both the right and left sides of the roadways. This left-to-go-left right-to-go-right scheme has since become obsolete, owing to the danger of merging into freeway traffic from the left. For this reason, there has been intermittent discussion about rebuilding the interchange.

The control cities and highways at the interchange are:

EAST: I-94, Downtown Milwaukee

SOUTH: I-894, US-45, Chicago

WEST: I-94, Madison

NORTH: US-45, Fond du Lac
