KHMA-TV was a short-lived independent television station in Houma, Louisiana that served the south Louisiana community.
 The FCC licensed channel 11 to St. Anthony TV Corporation in 1958, and the station was intended to be an ABC affiliate.
 In the 1960s, St. Anthony TV Corp. petitioned to move the station's transmitter to a point north of Houma near Geismar, LA so that the station could also serve Baton Rouge (which did not have a primary ABC affiliate yet).
 After the FCC granted permission to move the tower, both Louisiana Television Broadcasting Corporation (owner of Baton Rouge's then-NBC affiliate WBRZ, (now Baton Rouge's ABC affiliate) and Guaranty Broadcasting Corporation (owner of Baton Rouge's CBS affiliate WAFB) filed an appeal to block the transfer.
 In 1965, the District Court of Appeals ruled in favor of the two Baton Rouge stations, blocking the FCC's grant.
