Attack on Terror: The FBI vs. the Ku Klux Klan is a 1975 two-part television movie, which dramatised the events following the 1964 disappearance and murder of three Civil Rights workers in Mississippi. In this, it is similar in theme to the 1988 movie Mississippi Burning, though some names and details were changed, and both productions pick up the approximate storyline of the 1990 TV-movie Murder in Mississippi.

Attack on Terror starred Ned Beatty, John Beck, Marlyn Mason, Billy Green Bush, Dabney Coleman, Virginia Gregg, George Grizzard, Rip Torn, Sheila Larken, Hilly Hicks, and two M*A*S*H alumni, Wayne Rogers ("Trapper John") and Johnny Haymer ("Sgt. Zale").
