Star Realms is a card-based deck building science-fiction tabletop game, designed by Rob Dougherty and Darwin Kastle and published in 2014 by Wise Wizard Games. The game started out as a Kickstarter campaign in 2013. The goal of Star Realms is to destroy your opponent or opponents by purchasing cards using "trade" points and using these cards to attack your opponent's "authority" using your "combat" points. The game takes place in a distant future where different races compete to gain resources, trade and outmaneuver each other in a race to become ruler of the galaxy.

Star Realms is similar to other deck building games, like Ascension and Dominion.
