The 165th New York Infantry Regiment (aka, "2nd Battalion Duryée's Zouaves" and "Smith's Zouaves") was an infantry regiment in the Union Army during the American Civil War.
The regiment wore the same uniform as the 5th New York Infantry with the exception of the tassel of the fez, which was dark blue instead of yellow-gold.
Photographic evidence suggests that later in the war the 165th New York Infantry was given replacement sashes that were a solid red color without the light blue trim.
