Rolland William Redlin (February 29, 1920 – September 23, 2011) was a U.S. Representative from North Dakota, who served between 1965 and 1967.

He also served in the North Dakota Senate from 1959 to 1963 and later returned to serve again from 1973 until his retirement in 2000, as Senate President Pro Tempore 1987–9, and Minority Leadership later during his final 27 years' service.

In 1964, he ran for the U.S. House of Representatives and won, unseating incumbent Republican Don L. Short.

He has stated his vote for the 1965 Voting Rights Act was the accomplishment while serving in the US House of Representatives of which he is most proud, and that the breakdown of civil discourse in American politics during the past two decades is perhaps his greatest disappointment.

Redlin died on September 23, 2011, at his home in Rapid City.
