David R. Megarry is a game designer most notable for the board game Dungeon!.

Dave Megarry was a member of the Midwest Military Simulation Association, along with Dave Arneson, David Wesely, Ken Fletcher, John and Richard Snider and others. Megarry was also a member of Dave Arneson's original Twin Cities Blackmoor group.

Megarry designed a one-off board game called Dungeon! where players trooped through a dungeon on a singular basis, a game that had ultimately derived from the Braunstein playing sessions with Arneson. In November 1972, Arneson and Megarry traveled to Lake Geneva to meet with Gary Gygax, as Arneson thought that Gygax would be interested in Megarry's Dungeon! boardgame.Dungeon! was first published by TSR in 1975, and Megarry was hired by TSR in the same year.Dungeon! was the first adventure board game. Megarry called Bill Owen of Judges Guild to negotiate a formal license from September 4 – November 22, 1976; this agreement required Judges Guild to pay a royalty to TSR for the right to place text on the cover of most products saying "Approved for use with Dungeons & Dragons".

Arneson left TSR in 1976 over creative differences, and Megarry left around the same time.
