List of Kolchak: The Night Stalker episodes

This is an episode list for the original 1974-1975 television series Kolchak: The Night Stalker, produced by Universal Television for the ABC Television Network.

In 1972 and 1973, ABC had produced and aired two made-for-TV movies, which became the de facto pilots for the subsequent series. The original movie, based on an unpublished novel titled simply The Night Stalker, would spawn a direct sequel in the form of an episode of the series titled The Vampire. The second movie, The Night Strangler, however, was an entirely original story. The first episode of the series, The Ripper, is sometimes mistaken for the pilot of the series, and does share a number of plot similarities with the 2nd movie.

The series was originally given a full season order, but was cancelled after only 20 episodes were produced. Three additional scripts were written and in various stages of development at the time of cancellation and are included below as unproduced episodes.

The series resulted out of a rejected third movie script titled The Night Killers, whose plot involved aliens replacing government officials with androids. Though never produced, the series would address all three aspects of its plot individually in separate episodes.

Kolchak argues that a serial killer is actually Jack the Ripper.

Also known as "U.F.O." An invisible alien sucks down the bone marrow of its victims while it makes repairs and looks for directions home. This is the only story where Kolchak fails to stop the "monster."

A sequel to the first movie The Night Stalker. An overlooked victim of the Las Vegas vampire makes her way to Los Angeles and begins killing anew.

The ghost of an arsonist tries to take over a renowned conductor's body as his doppelganger.
