KNOW-FM (91.1 FM) is the flagship radio station of Minnesota Public Radio's news and information network, primarily broadcasting a talk radio format to the Minneapolis-St. Paul market. The frequency was the original home of KSJN, but the purchase of a commercial station at 99.5 MHz in 1991 allowed MPR to broadcast distinct talk radio and classical music services.

KNOW-FM's studios are located in the MPR Broadcast Center on Cedar Street in downtown St. Paul, while its transmitter is located on the Telefarm Towers in Shoreview.
