Unique was a hamlet in Weaver Township, Humboldt County, Iowa, United States.

The town contained a post office from April 1878 until September 1891.

[1] Settlers began building in the area when it was believed that a railroad would pass through the marshland.

The state of Iowa moved the post office in 1880, to its present-day location in the northeast corner.

The intersection of Humboldt County Route C44 (230th Street) and Humboldt County Route P29 (Florida Avenue) is often referred to colloquially as "Unique Corner".
