WTAF-TV was a television station broadcasting on channel 31 in Marion, Indiana, United States, between 1962 and 1969. An independent throughout its history, channel 31 was unable to develop a market between the established stations in Indianapolis and Fort Wayne, which impeded it from obtaining a network affiliation. Even though this crusade took an unexpectedly promising turn for the station, it did so too late to save it from bankruptcy and closure.
