Sorority House Massacre III: Hard to Die (also known as Tower of Terror or simply Hard to Die) is a 1990 American slasher film written by Mark Thomas McGee and James B. Rogers, directed by Jim Wynorski, and starring Gail Harris and Melissa Moore. The film features a similar storyline and many of the same actresses from its predecessor, and Wynorski's previous film Sorority House Massacre II, of which Hard to Die is essentially a remake.

The film was released direct-to-video in 1990, but it was released theatrically in 1992 under the name Tower of Terror and received an NC-17 rating. A sequel, titled Sorority House Massacre: The Final Exam, wrapped production in February 2002, but remains an unreleased film to this day.
