Larry and His Flask are a six-piece group from Redmond, Oregon, in the United States, active since 2003. Their sound combines bluegrass and folk with punk rock energy, and they are also associated with folk punk, folk rock, alt-country and punk.

The band performs with a fast, energetic style and uses acoustic instruments in a way that draws on rowdy bluegrass and folk traditions while keeping strong punk roots. Their music is also described as including a touch of gypsy soul. They are known for a live show that places all six members on stage at once and for playing at speed and with precision.

The group is recognised locally in Oregon and has built a strong following there. Their name is usually styled as Larry & His Flask.
