San Fierro Underground Radio (SF-UR) is a radio station in Grand Theft Auto: San Andreas which plays house music. It is hosted by the German house-music enthusiast Hans Oberlander (voiced by Lloyd Floyd).
SF-UR takes the identity of an underground radio, and as such it was probably meant originally to not feature any commercials (like other electronic music radios in previous games, like Rise FM and MSX FM), something that wasn't possible due to the way radio mechanics work in GTA San Andreas. Many of the earliest house-music acts in history are featured in its playlist. Much like Wave 103, SF-UR celebrates technology as its host happily exclaims, almost crying, "the computers have taken control! Isn't it beautiful? I think so, ya. Ya".
The host is Hans Oberlander, who is bilingual, being able to speak both English and German, occasionally alternating between the two during his commentary. Hans is a susceptible, insecure, loud and obnoxious guy who thinks his music is superior as he comments "it is any other music apart from house? I doubt it. Finally an electronic reality become believing". He takes a "rich and pretentious" role as he boasts of his parties in his condo that are "very exclusive, so exclusive that no one is invited". He has a drug habit and his emotionally unstable personality reflects it, his family also takes drugs as revealed when his father calls him to the radio. His father also criticizes his music and scolds him "son! This music's terrible! If you're going to be merciless, you have to send them beautiful Wagnerian operas."
As the name suggests, SF-UR is broadcast from a secret location in San Fierro.

- Two elements point towards that SF-UR probably was meant to be a pirate radio without commercials, in the vein of the electronic music radio MSX FM in GTA III.
- This is the only radio station which doesn't feature any station IDs, and the only radio station that doesn't have any renditions of the songs without the DJ commentary.
- Hans claims that SF-UR is commercial-free, despite that they do play (like in any of the radios).
- SF-UR plays inside Victim and Didier Sachs clothing stores.
- A Guy Called Gerald's "Voodoo Ray" and Frankie Knuckles' "Your Love" play in Nightclubs when not doing the dancing minigame.
- Hans said that he doesn't want to go rehab, and he said that "he's learning from watching his father". This quote can be heard in the '87 PSA commercial by Partnership for A Drug-Free America.
