Crandon is an unincorporated community in Spink County, in the U.S. state of South Dakota.
It was served by a branch line of the Chicago and Northwestern Railroad, which bisected the town's Main Street.
The branch connected Redfield to Huron by the James Valley Junction west of the latter.

[5] A post office was established at Crandon in 1881, and remained in operation until it was discontinued in 1935.
