Hudson Falls Historic District is a national historic district located at Hudson Falls in Washington County, New York.

The buildings were built between 1812 and 1935, the majority between 1875 and 1900, and reflect a variety of 19th and early-20th-century architectural styles.

Located within the district is the former Washington County Courthouse (1873) and the separately listed US Post Office-Hudson Falls.

One of the oldest structures is a law office building constructed about 1810 and located at 177 Main Street.

It is notable as having been the office for Henry C. Martindale (1780-1860) and his clerk, New York Governor Silas Wright (1795-1847).
