Longbranch Pennywhistle is an early-in-genre country rock album by Longbranch Pennywhistle, a duo featuring the then-little-known Glenn Frey and John David Souther. It also contains strains of folk rock. It was released in 1970; the duo split up shortly afterwards.
AllMusic's review of the album called it low-key and less commercial than the Eagles would be.
One of the album's songs, "Kite Woman", would resurface on Souther's 1972 debut solo album, John David Souther.
