Be a Brother is the third album by Big Brother and the Holding Company, released in October 1970.

It was their first album after Janis Joplin's departure.

Recruited in her place were guitarist David Shallock and singer-songwriters Nick Gravenites and Kathi McDonald.

Although "Home on the Strange" is credited as having been arranged and adapted by Peter Albin and Sam Andrew, it is in fact an original composition with no apparent derivation from any previous work.
