Star Trek: Secret of Vulcan Fury is a cancelled action-adventure game, in development by Interplay Entertainment from 1997 until its cancellation in 1999. Based on the Star Trek: The Original Series license, the game would have followed Captain James T. Kirk and the crew of the USS Enterprise through a series of adventures regarding the Vulcan and Romulan races. Secret of Vulcan Fury was to have been the latest in a series of games produced by Interplay based on the license. It would have featured a control method similar to those seen in LucasArts games of that period, and nearly seven hours of full motion video capture using clay models.

The storyline was written by former Star Trek writer D.C. Fontana, while the script was created by John Meredyth Lucas. A promotional cereal competition was run in conjunction with Quaker Oats, the first for the license in the United States. Despite this promotion, the game was cancelled with estimates placing it at only 5% completion. The cast of The Original Series had already recorded their voices. Lead engineer Thom Robertson later explained the studio had underestimated the cost of the game and the difficulties in filming the clay models.

The game was to be set in the 23rd century and across four independent stories which would have revolved around ancient secrets in the history of the Vulcan and Romulan races. The episodes allow the player to assume the roles of Captain James T. Kirk, Mr. Spock, Dr. Leonard McCoy, Lt. Hikaru Sulu, Ensign Pavel Chekov, and Engineer Montgomery "Scotty" Scott. The first episode was to involve the murder of a Romulan ambassador who was seeking to reunite the races, placing the player in control of Dr. McCoy initially.
