Puzzle & Action: Ichidant-R (also known as just Ichidant-R (イチダントアール?) is a puzzle video game developed and released by Sega in 1994 for the Sega System C.

The game was ported to the Sega Game Gear in 1994, Mega Drive in 1995, and released with Sega Ages compilations for the Sega Saturn and the PlayStation 2 (Rouka ni Ichidant-R and 2500 Vol.6 respectively). The game was released for the Wii Virtual Console in 2007. The game was re-released worldwide as part of the Sega Ages line. The third and final game in the series, Puzzle & Action: Treasure Hunt, was released in 1997.
