Niels Trolle til Trollesholm og Gavnø (20 December 1599 – 20 September 1667) was a Danish nobleman who served as vice admiral under Christian IV and later as Steward of Norway from 1656 to 1661.

In 1643, when the Torstensson War started, he served as a general provisioning commissioner until the spring of 1645, when Christian IV offered him the position of vice admiral.

In August, the Second Treaty of Bromsebro (Brømsebrofreden) was signed and in September he participated in the exchange of ratifications in Markaryd for which the fleet was unprepared.

He heard cases for Hannibal Sehested and Corfitz Ulfeldt, and in July was given a seat on the review commission to examine deliveries to Holmen.

Trolle had been strongly considered for Statholder of Norway in 1651 after Hannibal Sehested, and in 1656 he succeeded his brother-in-law Gregers Krabbe to the position.

Lieutenant General Jørgen Bjelke, commander-in-chief of the Norwegian army, was highly critical of Trolle's governorship due to his lack of support and inactivity during the second war with Sweden (1658–1660).

He settled in Copenhagen, but was not taken in any of the new management colleges, felt strongly infringed by the new ranking rules of 1662, and was regarded for several years as an opponent of the government.
