CHTN-FM is a Canadian radio station broadcasting in Charlottetown, Prince Edward Island, at 100.3 FM with a classic hits format branded as Ocean 100.

The station was launched on December 25, 1974, originally broadcasting from a bungalow on North River Road at 1190 AM before moving to 720 which was approved in 1987 [1] to eliminate the nighttime interference from WOWO, out of Fort Wayne, Indiana.

This precipitated a move by Newcap to surrender its AM licence and apply for its current FM frequency of 100.3, as well as open a new sister station, CKQK-FM.

The broadcast staff at the time were; Kirk & Kerri-Wynne (Mornings), Corey Tremere (mid-days), Gerard Murphy (Afternoons) and Gregg MacEwen (Evenings).

A free celebration pancake breakfast, with the morning show hosts on location in Tignish and Souris took place on Friday, March 5, 2010.
