A shot from the promo for the marathon.

Sci-Fi Channel's Thanksgiving Marathon (informally known as Turkey Day '97) is the only Thanksgiving marathon of Mystery Science Theater 3000 episodes run on the Sci-Fi Channel. It aired from 7:30 AM, November 27 to 4:00 AM on November 28, 1997.

In addition to not being officially named "Turkey Day" in the vein of the Comedy Central marathons, the marathon also lacked special promos and bumpers. Seven episodes, plus The Making of Mystery Science Theater 3000 were shown, along with a break for two Star Wars films.

The "Turkey Day" name would later be reinstated by Shout! Factory for online Thanksgiving marathons.
