Which is the largest county in New York? The answer depends on whether you mean area or population.

The counties, by shape

Every one, drawn to its own scale so the small ones stay recognisable. Shape alone is not a size comparison; the table below carries the areas.

What the map does not say

The counties of New York are nowhere near the same size. St. Lawrence County covers 2,680 sq mi of land, 118.3 times the 22.7 sq mi of New York County. People are spread even less evenly: New York County packs 73,478 per sq mi while Hamilton County holds 2.9 per sq mi.

They were not drawn in one sitting either. Westchester County dates to 1683, and the boundaries were still being redrawn when Bronx County was organised in 1914, 231 years later. Founding years come from Wikidata and are worth checking against the county's own history before citing.

Water is part of the picture too: 61.6% of Suffolk County is water, the most in the state, which is why its land area and total area disagree. And 37 of the 62 counties here share their names with counties in other states, so searching by name alone can land in the wrong place; the A to Z index lists every duplicate.

Sortable on any column. This table doubles as the text alternative to the map above: every area is a link, in alphabetical order, whether or not the map renders.
