Alaska Communications (formerly Alaska Communications Systems or ACS) is a telecommunications corporation headquartered in Anchorage, Alaska. It was the first telecommunications provider in the state of Alaska to maintain a third-generation wireless network and the only provider in Alaska that owned fully incorporated infrastructure for the major telecommunications platforms; wireless communications, Internet networking, and local and long distance phone service. Alaska Communications wireline operations include advanced data networks and a diverse undersea fiber optic system connecting Alaska to the contiguous United States. The Alaska Communications wireless operations included a statewide 3G CDMA network, and coverage extended from the North Slope to Southeast Alaska.

The company was formed in 1998, when CenturyTel announced the sale of its Alaska operations (newly acquired from PacifiCorp) to local management and Fox Paine & Company. In 1999, Alaska Communications acquired Anchorage Telephone Utility from the Municipality of Anchorage.

On February 3, 2014, Alaska Communications announced its purchase of TekMate, one of Alaska's leading managed information technology firms.

On December 4, 2014, GCI Wireless agreed to purchase the wireless assets of Alaska Communications for $300 million. The deal was completed in the first quarter of 2015.
