South Dakota Highway 17 (SD 17) is a 1-mile-long (1.6 km) state highway in southeastern South Dakota, United States.

It travels north along the eastern corporate limit of the town for one mile (1.6 km).

It ends at the intersection with 278th Street at the northeastern corner of the Lennox corporate limits.

[2] The original SD 17 was established in 1926, from west of Milbank to Peever.

In 2018, the South Dakota State Legislature removed the portion of SD 17 that ran from its current northern terminus up to SD 42 from the state highway system and turned it over to local control.
