QuinRose was a Japanese game developer specializing in otome games for Windows and consoles such as the PlayStation Portable. The company also produced drama CDs, manga, light novels, and other merchandise based on their games.

On September 25th 2015, Quinrose's parent company Artmove officially suspended business. Alleged reasons were the decline in sales due to the growing competitiveness in the marketplace, the growth of mobile games, and other factors. All games produced by Quinrose have ceased distribution since its business suspension.
