Altered Beast (獣王記 Jūōki, literally "Beast King's Chronicle", in Japan) is a 1988 arcade game developed and manufactured by Sega. After its initial arcade release, it was ported to several home video game consoles and home computers. Makoto Uchida was the primary developer of the game and also was responsible for the creation of Golden Axe.

Altered Beast is the fourth album by alternative rock musician Matthew Sweet. Released by Volcano Records in 1993, the initial response to this record was cool compared to Girlfriend, with Rolling Stone writing that the album was "[f]rustratingly uneven," with "inspiring moments; the problem is finding them."
