Project U.F.O. is an American television series which ran on NBC from 1978 to 1979. Running for two seasons of 13 episodes each, the show was based loosely on the real-life Project Blue Book. The show was created by Jack Webb, who pored through Air Force files looking for episode ideas.

The show was a production of Mark VII Limited in association with Worldvision Enterprises, now CBS Television Distribution and was Webb's last weekly series produced before his death. It was also one of the rare times that Webb did not produce a series with Universal Television or Warner Bros. Television; Webb collaborated with Universal for every series he made following his departure from Warner Bros., who had named him the president of its television division in the 1960s.
