Largest City in Area in the United States

While New York City is the most populous city in the United States, Sitka, Alaska is the largest city in area. Sitka includes a whopping 2874 square miles of incorporated area. The city is larger than the state of Delaware! Officially known as the "City and Borough of Sitka," the city consolidated the City of Sitka Borough in 2000 to be the country's largest city.

Sitka displaced Juneau, Alaska as the largest city upon the 2000 incorporation. Juneau is 2717 square miles and was formed through incorporation of the borough and city in 1970.

Sitka is a perfect example of an "overbounded" city, which refers to a city that has boundaries that extend far beyond its developed area (certainly the glaciers and ice fields in the city won't be developed soon.)

Jacksonville, Florida is the largest city in area in the contiguous 48 states at 758 square miles. Jacksonville includes all of Duval County, Florida with the exception of the beach communities (Atlantic Beach, Neptune Beach and Jacksonville Beach) and Baldwin.
