- "Targetting an entire generation of apathetic, despondent, trust-fund babies. Radio X..."
- — Station jingle
- "Finally, there IS an alternative. The home of Modern Rock. This is a revolution. Guitars, nihilistic hedonism, and telling the elder generation to go screw themselves. Nobody has done this before. We are original thinkers. We are free. Sage leads the navel gazing; she is a remarkable talent."

Radio X (styled as Radio:X in its logo) is a radio station in Grand Theft Auto: San Andreas that plays alternative rock, grunge, hard rock and alternative metal. It is hosted by Sage (voiced by Jodie Shawback).
Radio X is full of the 1990s grunge attitude and of the Generation X vibe of the time. Its host, Sage, presents an intellectual, nihilist, revolutionist and pessimistic character.
The station's tracklist represents many of the contemporary modern/alternative rock sounds that were prominent or emerging in the early 1990s. The most represented genre on the station is undoubtedly grunge, with bands like L7, Soundgarden, Alice in Chains, and Stone Temple Pilots all having songs on the station, as well as the grunge energy given off by both the station idents and Sage. Also exhibited on the station are major heavy metal and hard rock acts from the late 1980s and early 1990s, like Guns 'n' Roses, Danzig, and Ozzy Osbourne (unavailable on rerelease versions). The alternative metal scene is also on display, from acts such as Helmet, Living Colour, Alice in Chains, Faith No More, and Rage Against The Machine (not on rerelease versions). Interestingly, this alternative metal group mainly features acts that would serve influential to nu metal later in the 1990s, a genre that has yet to appear on GTA radios. The station also features softer, more dance-oriented songs by acts like Depeche Mode, Primal Scream, and The Stone Roses, representing the sounds of early 1990s UK alternative scenes such as synth-rock, Madchester, and neo-psychedelia. There is also a funk rock undertone to some acts, namely Jane's Addiction, The Stone Roses, Primal Scream, and Faith No More.
Through its idents it boasts that "finally there is an alternative to commercial rock, these guys don't care about money". It also says that it is "the birth of modern rock and fundamental social upheaval" and that "the end of civilization is here". It attacks the older generation, the baby boomers, and its music, saying "anyone who doesn't think this is the best music recorded in history, should just jump off a bridge and die".
It also humorously pokes fun of the self-centered attitude of its listeners, with idents that say "we are self-important nihilists", "who cares about poverty, we got egos to worry about", "we're the end of the alphabet people, that's got to mean something, but we don't know what", and "the id, the ego and now the X".
It also calls its listeners "apathetic, despondent, trust-fund babies" and tells them pessimistic comments like "nothing that you'll ever do will ever mean anything, we're the only identity you've got" and "feel like you mean something".
The station's host, Sage, is a young woman and proud member of Generation X. She is an escaped mental patient who is very opinionated and constantly speaks her views in-between songs. She gets lost frequently in her random musings, displaying extremely pessimistic and narcissistic views. She constantly wants to have sex and hates the older generations so much that she wants to kill anyone over the age of 30. She isn't very popular, as callers criticize her photography exhibition as "full of weird and stupid photos where they lick coloring books". She constantly says she wants to die and threatens to set herself on fire when all the bridges in San Andreas are open, permitting the player access to all areas in the game. Sage celebrates the riots in the later stages of the game, believing they are part of her "end of the world revolution".
