"Mama, I'm Coming Home" is the third song on the 1991 album No More Tears by the English heavy metal singer Ozzy Osbourne. The power ballad is about his wife and manager, Sharon Osbourne, whom he nicknames "Mama", and his return to her following his imminent retirement. The song was co-written by Zakk Wylde, Osborne's longtime guitarist, frontman and lead guitarist for heavy metal group Black Label Society, and Lemmy Kilmister, frontman of the heavy metal group Motörhead. Lemmy was brought in as a songwriter for the No More Tears album, providing lyrics for the tracks "Mama I'm Coming Home", "Hellraiser" (which Motörhead also later recorded), "Desire", and "I Don't Want to Change the World."
Two music videos were created for the single. The first was a surreal video that Osbourne didn't like because he felt the video didn't match the song. He then created a second music video with Samuel Bayer, which was more to his liking. Osbourne compared the effects in the second video to the hazy smoke effect seen in the video for Nirvana's "Smells Like Teen Spirit", which was also directed by Bayer.
