The 2015 Eastern Washington Eagles football team represented Eastern Washington University in the 2015 NCAA Division I FCS football season. The team was coached by Beau Baldwin, who was in his eighth season with Eastern Washington. The Eagles played their home games at Roos Field in Cheney, Washington and were a member of the Big Sky Conference. They finished the season 6–5, 5–3 in Big Sky play to finish in a four way tie for fourth place. They failed to reach the FCS Playoffs for the first time since 2011.
Despite Montana State also being a member of the Big Sky Conference, the September 19 game against Eastern Washington was considered a non-conference game.
