The third season of the action-adventure television series The A-Team premiered in the United States on NBC on September 18, 1984, and concluded on May 14, 1985, consisting of 25 episodes.
 Tawnia Baker, the A-Team's support member for the last half season calls in the help of her friends to find an archaeologist (secretly her fiancé) that has gone missing during an Amazon expedition. Traveling to the Amazon, the A-Team must deal with the local pirate king, "El Cajon" (The Coffin).  The A-Team have to find a way to locate the pirates, bringing them into unknown territory. Locating the pirates, they come across a plot that is far greater than any of them could have expected: Third Reich remnants building a nuclear station. As Murdock puts it "the Fuhrer the better." The A-Team must ally themselves with the shady El Cajon's forces to defeat the threat. This is the last appearance of Tawnia Baker, who weds her fiancé at the end of the episode.
 A fire chief calls in the help of the A-Team to help defend her department from a competing fire fighting department. Meanwhile, Colonel Decker is temporally replaced by a Colonel named Briggs, who opens his hunt on the A-Team, only to be unsuccessful in his first and only attempt.
