The 2015-16 season was Colchester United's 79th season in their history and their eighth consecutive season in League One, the third tier of English football. Along with competing in League One, the club will also participate in the FA Cup, League Cup and Football League Trophy. The club suffered relegation to League Two, the fourth tier of English football, for the first time in 18-years after finishing the season in 23rd position and in the relegation zone. Colchester made an early exit in the League Cup at the hands of Reading, while they made the fourth round of the FA Cup for the first time in ten years but were defeated by Premier League side Tottenham Hotspur 4-1. The season was notable for managerial changes. Tony Humes began the season in charge, but after a string of successive defeats, he left by mutual consent in November. Richard Hall and John McGreal took temporary charge for one match before they were replaced by Wayne Brown. Kevin Keen took up the reins in December but was unable to transform the U's fortunes, and they were relegated under his stewardship. He left with two games of the season after relegation was confirmed, and his assistant David Wright was placed in the caretaker position. McGreal was then named Keen's permanent successor ahead of the final game of the season, but would not take charge until the season had ended. This meant McGreal's new assistant manager, Steve Ball, managed the side for the last game of 2015-16.
