Season summary
St Mirren began the season under the management of Jim Goodwin in his second full season at the club. In July 2021, St Mirren announced that they would now be a fan-owned club after chairman Gordon Scott agreed to sell his majority shareholding to the St Mirren Independent Supporters Association (SMISA). John Needham was then appointed as the new chairman of the club. On 19 February, Jim Goodwin would leave his position as manager to take up the vacant manager's position at Aberdeen. On 22 February, former Motherwell manager Stephen Robinson was appointed as the club's new manager on a two-and-a-half-year deal.
