The Saturn Award for Best Horror Television Series is one of the annual awards given by the American Academy of Science Fiction, Fantasy & Horror Films. The Saturn Awards, which are the oldest film and series-specialized awards to reward science fiction, fantasy, and horror achievements, included the category for the first time at the 42nd Saturn Awards ceremony, when the Saturn Award went through major changes in their television categories. It specifically rewards horror on television.

The Walking Dead was the only series to win from the award's introduction in 2016 until 2024, when The Last of Us won. The award received a sister category for streaming series in the horror and thriller genres in 2019 and 2021, awarded to Stranger Things in both years.
