Mississippi Public Broadcasting is the public broadcasting network in Mississippi, United States. Owned by the Mississippi Authority for Educational Television, it holds the licenses for all of the PBS and NPR stations in the state.

Mississippi was a relative latecomer to public broadcasting. WMAA-TV began operating in Jackson as the first-ever public broadcasting station in the state. The inaugural broadcast took place in summer 1970. The initial broadcast written by Jeanne Lucket, produced and directed by Mims Wright, then Director of Public Affairs at WLBT. This made Mississippi the last state east of the Mississippi River to start public television service within its own borders. Before then, the only portions of the state to get a clear signal from a PBS station were the northwest (from Memphis' WKNO-TV) and the Gulf Coast (from New Orleans' WYES-TV and Mobile's WEIQ). Six other stations signed on over the next few years, and the network became known as Mississippi Educational Television, or simply ETV. Public radio was even later in arriving in the state, in 1984. Eventually, Public Radio in Mississippi expanded to eight stations throughout the state.

In 2005, MAET adopted "Mississippi Public Broadcasting" as an umbrella on-air name for all television and radio operations.

Notes:

• 1. WMPN-TV used the callsign WMAA-TV from its 1970 sign-on until 1990.

Mississippi Public Broadcasting also operates two translator stations: W45AA in Columbia and W47BP in Hattiesburg.

Mississippi Public Broadcasting has also operated a microwave-relay station KMZ 77 for many years. This special microwave station has been used as a studio-to-transmitter link (STL) for WMPN-TV in Jackson. During the weekly signoff message (formerly nightly signoff message), KMZ 77 would be mentioned following the technical specifications of WMPN-TV. KMZ 77 was also mentioned in the same manner during the time prior to 1990 when WMPN-TV carried the call sign of WMAA-TV. Each station in the network and KMZ 77 would be identified in the network's signoff message as being owned and operated by the Mississippi Authority for Educational Television.

Although the FCC apparently granted MPB a permit to build WMAA-DT, a digital-only station near Columbus, MPB has stated there are currently no plans or funding to build the station.
