"Sirius" is an instrumental by British rock band the Alan Parsons Project, recorded for their sixth studio album, Eye in the Sky (1982). Nearly two minutes long, it segues into "Eye in the Sky" on the original recording. From the 1990s onward, "Sirius" has become a staple of many college and professional sporting events throughout North America, most prominently Chicago Bulls and Nebraska Cornhuskers games.

The Alan Parsons Project were a British rock band active between 1975 and 1990, whose core membership consisted of producer, audio engineer, musician and composer Alan Parsons and singer, songwriter and pianist Eric Woolfson. They were accompanied by varying session musicians and some relatively consistent session players such as guitarist Ian Bairnson, arranger Andrew Powell, bassist and vocalist David Paton, drummer Stuart Elliott, and vocalists Lenny Zakatek and Chris Rainbow. Parsons and Woolfson shared writing credits on almost all of the Project's songs, with Parsons producing or co-producing all of the band's recordings.
