The Caldwell Historic District in Caldwell, Idaho, is an area of approximately four acres in downtown Caldwell along Main Street, South 7th Avenue, South Kimball Avenue, and Arthur Street.

[5] The district includes Romanesque Revival and modest commercial architecture, although some facades have been altered since construction.

The 1982 site survey noted 14 buildings, and the district was added to the National Register of Historic Places (NRHP) July 19, 1982.

[56] By that time, 1st Avenue West may have become known informally as Bank Street.
