Loren Dwight Leman (Russian: Лорен Дуайт Леман; born December 2, 1950) is an American politician who served as the eighth lieutenant governor of Alaska, from 2002 to 2006.

Leman was born in Pomona, California, and grew up in Ninilchik, Alaska, in a Russian-speaking family of Alutiiq, Russian Creole, and Polish ancestry.

Leman traces his long family history in Alaska to the marriage in Kodiak in 1798 between a Russian shipbuilder and an Alutiiq woman from Afognak.

As lieutenant governor, Leman continued his interests in budget discipline, education accountability, promoting wise use of Alaska's natural resources, and supporting the right to life.

A social conservative, he led efforts to require parental notification for girls seeking to have abortions and was a prime sponsor of a 1998 Alaska constitutional amendment that defined marriage as between one man and one woman.

He represented the State as one of seven commissioners on the Denali Commission, a unique State-federal cooperative effort to improve health care, energy, transportation, economic opportunities and workforce development, primarily in rural Alaska.

A few days later, Leman declined a run for the office (saying Murkowski's decision was only one of many factors) and also opted out of a second term as lieutenant governor.

He has managed projects to improve airports, was an early supporter of the Alaska Aerospace Development Corporation's launch facilities on Kodiak, served on the board of directors of the Challenger Learning Center in Kenai, and as the national chairman of the Aerospace States Association, an organization of lieutenant governors and governor-appointed delegates from space ports and academia who advise Congress on aviation and space issues.

He was a sponsor of legislation to enable the Alaska Railroad to complete a track realignment and improvement project from Ship Creek to Wasilla.
