Dennis William Egan (March 3, 1947 – June 28, 2022) was an American politician who was a member of the Alaska Senate representing Juneau from April 19, 2009, until January 15, 2019.

[2] He was the son of Bill Egan, a politician active in Alaska Territory who would go on to service as the state's first and fourth governor, and Neva Egan (née Desdia Neva McKittrick), who served as First Lady of Alaska during her husband's time as governor.

[7] Dennis's first attempt at politics happened in the 1980s, when he ran a primary election bid for a seat in the Alaska House of Representatives; he lost to Bruce Botelho.

Bob Tkacz of the Anchorage Press had an unfavorable view of the Empire's support of the Derby and Egan's efforts to end the boycott.

[11] In September 1997 Egan helped keep 200 United States Forest Service jobs from being moved from Juneau to Ketchikan.

[14] Governor Sarah Palin chose to appoint Tim Grussendorf, Chief of Staff to Senator Lyman Hoffman, to the seat over State Representative Beth Kerttula who was the preferred choice of local Democratic Party.

In April 2009, Egan was appointed to the Alaska Senate by Governor Sarah Palin to replace Kim Elton, who resigned in March 2009.

[16] In the 2010 election, Egan ran against token write-in opposition, winning a full term with 96% of the vote.
