Duane Ankney (born April 14, 1946) is a Republican member of the Montana Senate representing District 20.

In 2015, Ankney introduced Senate Bill 402, which would have required utilities to pay an impact fee to close a power plant before 2025.

Portions of the revenue made from the fee would have gone to school districts and the Montana Department of Commerce.

The bill failed on a 49–49 vote in the Montana House of Representatives.
