The mattberry was a species of berry that could be located on the moon called Endor. In the year 4 ABY, the succulent mattberries thrived together with ferns and tree palms covering the forest ground under Bright Tree Village, which was an Ewok village located in the treetops of Endor. The Ewoks would occasionally descend to the forest floor to gather fruits and different kinds of berries.
Within current Star Wars canon, mattberries received a mention in the reference book Star Wars: Complete Locations from 2016. The berries's origins are in the Star Wars Legends timeline, with their initial mention appearing in Galaxy Guide 5: Return of the Jedi, a 1990 sourcebook penned by Michael Stern for the Star Wars: The Roleplaying Game by West End Games.
