WTHI-FM (99.9 FM; "HI-99") is a radio station running a country music format in Terre Haute, Indiana. The station's studios and broadcast tower are located along Ohio Street in downtown Terre Haute. The station is owned by Midwest Communications.[1]

WTHI-FM has led the Terre Haute market ratings for over twenty years. In 2007, the station celebrated 25 years in the country format. Over the years, WTHI has raised more than $1,000,000 for the kids at St. Jude Children's Research Hospital.

WTHI-FM's former studio building, which was shared with sister station WWVR and former sister station WTHI-TV (which was co-owned with WTHI-FM from 1954 to 2005), is being demolished in December 2012 to accommodate parking for a new office building constructed behind the former WTHI building and facing Wabash Avenue.[2] The old building was constructed as a garment factory in 1906, but housed WTHI-FM and WTHI-TV from 1954 to 2012.[3] WTHI-FM and WWVR, which were later joined by new acquisitions WFNF/1130 AM and WFNB/92.7 FM, moved into their new office building in August 2012;[2] this separated the stations from WTHI-TV,[3] which moved to its own new building (at 800 Ohio Street) in October 2012.[2]
