KIOI (101.3 FM, "Star 101.3") is a hot AC-formatted radio station licensed to San Francisco, California and owned by iHeartMedia, Inc.^[1] The radio studios and offices are in the SoMa district of San Francisco.

KIOI has an effective radiated power (ERP) of 125,000 watts. It is considered a "superpower station" due to this unusually high wattage that is grandfathered into KIOI's license.^[2] It is one of two stations in San Francisco broadcasting with more than 100,000 watts, the other being KQED-FM, with 110,000 watts. KIOI's transmitter is on Radio Road in Daly City, amid the towers for other San Francisco-area FM and TV stations.^[3] It also has booster stations on 101.3 MHz in Walnut Creek and Pleasanton.
