At the 1900 Summer Olympics in Paris, many shooting events were featured within the concurrent 1900 Exposition Universelle, but only eight events currently are considered as "Olympic" by IOC.

The competitions were held from 3 August to 5 August and took place at the military sporting complex in Satory and at Boulogne-Billancourt.
