CHSN-FM is a Canadian radio station broadcasting at 102.3 FM in Estevan, Saskatchewan.

The station is currently owned & operated by Golden West Broadcasting and plays a hot adult contemporary format under the brand name Sun 102.

Golden West received approval from the CRTC[1] on April 26, 2001, and the station was launched in November of the same year.

CHSN's format, branding and call sign were all adopted from a radio station in Saskatoon whose owner, Rawlco Communications, dropped them to launch a new active rock station, CJDJ.

In 2012, following the launch of CKSE-FM, CHSN switched to a hot adult contemporary format, with a much heavier emphasis on Top 40 pop.
