300 m standard rifle is one of the ISSF shooting events. It is similar to 300 metre rifle but there are more restrictions on the rifle. The course of fire is a three positions program of 3x20 shots. This event is based in competitions with army-style rifles, and as such dates back at least to the 19th century, although the early championships had a true army rifle event, using the model of the host country's choice. The standard rifle event as such was created in 1947.

The International Shooting Sport Federation recognizes several shooting events, some of which have Olympic status. They are divided into four disciplines: rifle, pistol, shotgun and running target.
