Interstate 535 (I-535) is a 2.78-mile-long (4.47 km) Interstate Highway spur route of Interstate 35 in Minnesota and Wisconsin, in the United States. It is paired with U.S. Highway 53 (US 53) along its entire route.

I-535 begins in the city of Superior, at the junction of US 53 and Wisconsin Highway 35 (WIS 35) and continues northwest across the John Blatnik Bridge over the Saint Louis Bay of Lake Superior. The freeway crosses from Wisconsin into Minnesota on the bridge and then meets an interchange for Garfield Avenue and the Port Terminal in the city of Duluth. I-535 ends at the junction of US 53 and I-35 known locally as the "Can of Worms" interchange, which features a pair of left exits from I-35, a stoplight, and lane drops over the I-35 bridge.

I-535 is the shortest Interstate in both Minnesota and Wisconsin. It also is the only Interstate in the two states with no exit numbers. I-535 in Wisconsin is one of the few instances in the United States of a three-digit Interstate Highway entering a state that its parent two-digit Interstate does not enter. Other examples include Interstate 275 near Cincinnati, Ohio, Interstate 287, and Interstate 129.
