"Untouchable" is a posthumous single by 2Pac, featuring Krayzie Bone, from the album Pac's Life. Remixed by Swizz Beatz, it was the street-single released opposite the lead-single, "Pac's Life". The single debuted at number 111 in billboard 200 and number #91 on the Hot R&B/Hip-Hop Singles & Tracks and #21 on Hot R&B/Hip-Hop Singles sales on the December 2, 2006 issue of Billboard magazine. The record contains lyrics similar to other 2Pac songs, such as: "Untouchable freestyle", "Killuminati" and "War Gamez".

"Killuminati" was recorded on 8 July 1996 for The Don Killuminati: The 7 Day Theory, but didn't make the final cut, and was released in 1999 in remixed form on Still I Rise.

A pre-mix of the original version leaked onto the internet which features Hussein Fatal and E.D.I. Mean. The final mix of the original, with Yaki Kadafi and Storm, has yet to leak, although a snippet of Kadafi's verse over the original beat is available.

The album version, remixed by Sha Money XL, is the last song featured on the album with guest appearances by Jamal "Gravy" Woolard, Yaki Kadafi and Hussein Fatal.

The unreleased, but leaked "Untouchable (Freestyle)" is a version recorded after the initial sessions for the song "Untouchable". The instrumental itself was remixed to a more "live" setting with 2Pac laying down vocals while heavily intoxicated.

"Untouchable" was first issued on Lisa "Left Eye" Lopes' album Supernova, using the instrumental from the original version with vocals from 2Pac from both the song and its freestyle version.

In 2002, the song was re-mixed and re-recorded for Lopes' unreleased second studio album N.I.N.A.. It was released as a promotional single for the album.
