Pompeo Gabrielli (22 August 1780 – 28 March 1861) was an Italian general and politician, the first layman to be appointed Minister in a Papal States cabinet.

Pietro's brother (Pompeo's uncle) was Cardinal Giulio Gabrielli the Younger, who served as Pius VII's Secretary of State.

In 1825, with the rank of colonel of the Dragoons, he headed all the military forces deployed in the Legations but refrained from taking too severe measures against the insurgents, rather seeking pacification by diplomatic means.

Among the factors contributing to his selection were the consideration that he had manifested "modern" views by serving under Napoleon in his youth, but had also shown capacity and loyalty to the Pope since the Restoration.

With the proclamation of the Roman Republic in 1849 he retired from public life, but in 1850 welcomed the return of Pius IX to Rome and escorted him from the State border to the Quirinal Palace.
