Nick G. Sibbeston (born November 21, 1943)[1] is a retired Canadian politician, serving from 1985 to 1987 as the fourth premier of the Northwest Territories.

Sibbeston was a Senator representing the Northwest Territories from 1999 until 2017, when he resigned on his 74th birthday, a year prior to reaching the mandatory retirement age.

After 1991, Sibbeston worked briefly for the Government of Northwest Territories, as a justice specialist and as a public administrator for Deh Cho Health & Social Services.
