KZDC (1250 AM, "ESPN 1250") is an all-sports-formatted radio station in San Antonio, Texas, owned by Connoisseur Media. Most of the programming comes from ESPN Radio. Its studios and offices are located on Eisenhauer Road in Northeast San Antonio.

KZDC broadcasts at 25,000 watts by day using a non-directional antenna. To avoid interfering with other stations on 1250 AM, it drastically reduces power at night to 920 watts and uses a directional antenna. The daytime transmitter site is just off U.S. Route 281 near Interstate 410, in the Mission del Lago district of San Antonio. The station uses a separate nighttime site which is co-located with sister station KTSA, along Eisenhauer Road in Northeast San Antonio, across the street from the studios.
