WOWfm 100.5 (ACMA call sign 5WOW[1]) is a community radio station based in Semaphore, South Australia, named in reference to its location in Adelaide's Western suburbs.

From 1994 through 2000, WOWfm held a number of short-term licences under the Australian Communications and Media Authority (ACMA) Temporary Community Broadcasting Licence (TCBL) scheme, broadcasting on 100.7 MHz.

[3] In October 2005, WOWfm's studios were the subject of an arson attack, causing $50,000 worth of damage[5] and taking the station off-air for at least two weeks.
