Osmium is the debut album of American funk band Parliament, led by George Clinton. The album has a psychedelic soul sound with a spirit of experimentation that is more similar to early Funkadelic than the later R&B-inspired Parliament albums. It was originally released in July 1970 on Invictus Records. The original vinyl release contained a glossy lyric sheet.

Parliament was an American funk band formed in the late 1960s by George Clinton as a flagship act of his P-Funk collective. Evolving out of an earlier vocal group, Parliament became associated with a more commercial and less rock-oriented sound than its sister act Funkadelic. Their work incorporated Afrofuturism concepts, horn arrangements, synthesizer, and outlandish theatrics. The band scored a number of Top 10 hits, including the million-selling 1976 single "Give Up the Funk ," and Top 40 albums such as Mothership Connection (1975).
