Bachman–Turner Overdrive is a Canadian rock group from Winnipeg, Manitoba, that had a series of hit albums and singles in the 1970s, selling over 7 million albums in that decade alone. Their 1970s catalogue included five Top 40 albums and six U.S. Top 40 singles (ten in Canada). The band has sold nearly 30 million albums worldwide, and has fans affectionately known as "gearheads" (derived from the band's gear-shaped logo). Many of their songs, including "Let It Ride", "You Ain't Seen Nothing Yet", "Takin' Care of Business", "Hey You" and "Roll On Down the Highway", still receive play on classic-rock stations.

After the band went into a hiatus in 2005, Randy Bachman and Fred Turner reunited in 2009 to tour and collaborate on a new album. In 2010, they played the halftime show at the Grey Cup in Edmonton, AB and continue to tour as of summer 2014.

On March 29, 2014, The classic "Not Fragile" line up reunited for the first time since 1991 to accept the JUNO Award for Bachman–Turner Overdrive and participated in performing in a tribute version of "Takin' Care of Business."

The precursor to BTO was the band Brave Belt, formed in Winnipeg in 1971 by Randy Bachman and Chad Allan, both formerly of The Guess Who, and drummer Robin "Robbie" Bachman. Randy initially planned to just produce a solo album for Allan, but eventually both he and Robbie stepped in to provide much of the instrumental work. When the record label wanted them to tour, Randy (at the suggestion of Neil Young) called fellow Winnipeg bassist/vocalist C.F. "Fred" Turner to perform in the band's scheduled gigs.

After their demo tape had been rejected 26 times (sometimes more than once by the same label), Bachman was prepared to tell the other band members that they would no longer be able to remain on salary, "And they had to go and get the dreaded day jobs". However, in April 1973, Charlie Fach of Mercury Records returned to his office after a trip to France to find a stack of unplayed demo tapes waiting on his desk. Wanting to start completely fresh, he took a trash can and slid all the tapes into it except one which missed the can and fell onto the floor. Fach picked up the tape and noticed Bachman's name on it. He remembered talking to him the previous year and had told Bachman that if he ever put a demo together to send it to him.

Fach convinced the band that a brand new name was needed; one that capitalized on the name recognition of the band members. The band had already mulled over using their surnames. While on their way back from a gig in Toronto, the group had spotted a copy of a trucker’s magazine called Overdrive at a Windsor, Ontario truckstop, after which Turner wrote "Bachman–Turner Overdrive" and the initials "B.T.O." on a serviette. The rest of the band decided the addition of "Overdrive" was the perfect way to describe their music.
