The 1986 United States Senate election in Alaska was held on November 4, 1986. Incumbent Republican United States Senator Frank Murkowski ran for a second term in the United States Senate and was primarily opposed by Alaska Pacific University President Glenn Olds. Following a highly competitive election in 1980, Murkowski faced a legitimate opponent in Glenn Olds, and the contest was fairly close. However, in the end, Murkowski was able to defeat Olds by a slightly wider margin than he won by six years prior.
