San Francisco International Airport is a television drama that was originally aired in the United States by NBC as a part of its 1970–71 wheel series Four in One.

The series starred Lloyd Bridges as Jim Conrad, the manager of the gigantic San Francisco International Airport, which at the time of the series aired was said to handle more than 15,000,000 passengers annually and have more than 35,000 employees. Bob Hatten (Clu Gulager) was his chief of security, an important role at a time when security was beginning to emerge as a real-life major issue in air transport. June (Barbara Werle) was Conrad's secretary. Airport situations drawn from real life were addressed, such as protesting demonstrators, mechanical malfunctions, and similar problems.

The show's pilot, also called San Francisco International Airport or simply San Francisco International, had aired as a TV movie and starred Pernell Roberts in the role of Jim Conrad. The network ordered six series episodes, but only with the stipulation that Bridges play the role instead of Roberts.

San Francisco International Airport was the second program in the Four in One rotation, following McCloud. The six episodes were first shown in order from late October until early December, 1970, and were then replaced in the Wednesday night 10 pm Eastern time slot by Night Gallery. Once Night Gallery and The Psychiatrist had completed their first runs, episodes of all four series were rerun interspersed with one another. Night Gallery was picked up for the next season as a stand-alone series and McCloud was renewed as an element in a new wheel series, NBC Mystery Movie, but San Francisco International Airport and The Psychiatrist were cancelled, with no more episodes ordered beyond the initial six.

The pilot, starring Roberts, got lukewarm reviews and was largely forgotten for years, but it was eventually rescued from obscurity by becoming the subject of a sixth-season episode of Mystery Science Theater 3000 in 1994.
