The Isle of Man Rifle Association (IoMRA) is the governing body for smallbore rifle shooting in the Isle of Man. It has eight clubs affiliated to it: seven indoor and one outdoor. The Association organises a wide range of inter-club and individual competitions throughout the year, with most activity taking place during the winter months. Its major focus is on the Winter shoulder-to-shoulder league.

The Association also owns the Sinclair Range, a high standard 50 metre facility at St John's, where outdoor smallbore shooting organised by the Isle of Man Shooting Club takes place all year round and where the rifle events of the highly successful Easter Shooting Festival take place.
