Leonia is a borough in Bergen County, in the U.S. state of New Jersey. As of the 2020 United States census, the borough's population was 9,304, an increase of 367 (+4.1%) from the 2010 census count of 8,937, which in turn reflected an increase of 23 (+0.3%) from the 8,914 counted in the 2000 census. The borough is a suburb of New York City, near the western approach to the George Washington Bridge.

Leonia was formed as the result of a referendum passed on December 5, 1894, from portions of Ridgefield Township. The borough formed during the "boroughitis" phenomenon then sweeping Bergen County, in which 26 boroughs were formed in the county in 1894 alone. Portions of Leonia were taken on February 19, 1895, to form the Township of Teaneck.

New Jersey Monthly magazine ranked Leonia the 31st-best place to live in its 2008 rankings of the "Best Places To Live" in New Jersey.
