1987 Washington State Cougars football team

The 1987 Washington State Cougars football team was an American football team that represented Washington State University in the Pacific-10 Conference (Pac-10) during the 1987 NCAA Division I-A football season. In their first season under head coach Dennis Erickson, the Cougars compiled a 3–7–1 record (1–5–1 in Pac-10, ninth), and were outscored 356 to 238. Home games were played on campus at Martin Stadium in Pullman, Washington.

The team's statistical leaders included Timm Rosenbach with 2,446 passing yards, Richard Calvin with 822 rushing yards, and Steve Broussard with 701 receiving yards.

After nine years as WSU head coach, Jim Walden departed for Iowa State in the Big Eight Conference in late 1986,  and was succeeded by Erickson, who returned to the Palouse in January 1987 after just one season at Wyoming; he had led neighboring Idaho for the previous four years. Wyoming visited Pullman in the second week of the season, a fifteen-point Cougar victory.
