Cooper Robert Rush (born November 21, 1993) is an American professional football quarterback. He played college football for the Central Michigan Chippewas, and was signed by the Dallas Cowboys as an undrafted free agent in 2017.

Originally from Charlotte, Michigan, Rush attended Lansing Catholic High School in Lansing, Michigan, with an enrollment of just over 500 students, where he became a three-year starter at quarterback for the football team. Rush also played basketball and baseball (until his freshman year).

In 2010 and 2011, Rush led his team to back-to-back undefeated regular seasons. In 2011, Rush led his team to the state runner-up title. In the Division 5 regional championship game against Dowagiac Union High School, he set Michigan state records with five touchdown passes in one quarter and eight for the game. The team would end up losing in the finals against Powers Catholic High School 56–26, even though Rush registered 300 passing yards and three touchdowns.

As a senior, Rush received All-State, Associated Press' Michigan Division 5/6 Player of the Year and ESPN's Michigan Gatorade Player of the Year honors.

Rush finished his high school career throwing for 7,248 passing yards (455-for-734, 62 percent) and 80 touchdowns to go along with 1,438 rushing yards and 27 touchdowns. A three-star recruit, Rush only received scholarship offers from Central Michigan and Toledo, but received preferred walk-on offers from Michigan, Michigan State, Northwestern, and Western Michigan.

In his redshirt season at Central Michigan, Rush was named the school's Scout Team Player of the Year.

As a freshman, although he began the season as the third-string quarterback, Rush was named the starter by the third game, after Cody Kater was injured (collarbone fracture) and his backup Alex Niznak could not move the offense against the New Hampshire Wildcats. In that contest, Rush came in in the second quarter and helped engineer a 24–21 comeback victory, where he tallied 326 passing yards and three touchdowns, tying the school record for the longest in history (97 yards). Rush would never relinquish the position or miss a start after the game.

As a sophomore, Rush played in the 2014 Bahamas Bowl against the Western Kentucky Hilltoppers. By the middle of the third quarter, his team had fallen behind 49–14, but scored four unanswered touchdowns and were down by only seven points near the end of the fourth quarter. With one second remaining in the contest, Central Michigan had the ball on their own 25 yard line. The would-be final play started with a 45-yard Hail Mary pass from Rush to wide receiver Jesse Kroll. As Kroll was being tackled he lateraled the ball to teammate Deon Butler, who ran 20 yards before lateraling to Courtney Williams. With no space to run, Williams made a quick third lateral pass to leading receiver Titus Davis who ran the final 13 yards, scoring a touchdown that would have tied the game with a kicked extra point and sent the game into overtime, but instead Central Michigan attempted a two-point conversion for the win, which was unsuccessful. Had the try succeeded, it would have marked the largest comeback in bowl history and tied the largest comeback in any Division I game. Rush's seven touchdown passes set an all-time record for all bowl games.
