The Boswell Sisters were a singing group that attained national prominence in the USA in the 1930s.

Sisters Martha Boswell (1905-1958), Connie Boswell (December 3, 1907-October 11, 1976), and Helvetia "Vet" Boswell (May 20, 1911 - 1988) were born in a middle-class family on Camp Street in uptown New Orleans, Louisiana.

They came to be well known locally while still in their early teens, making appearances in New Orleans theaters and radio. They made their first recordings for Victor Records in 1925. They did not attain national attention, however, until they moved to New York City in 1930 and started making national radio broadcasts. After a few recordings with Okeh Records, they made numerous recordings for Brunswick Records throughout the 1930s.

Connie Boswell continued to have a solo career as a singer after the sister act broke up.

The Andrews Sisters started out as Boswell Sisters imitators. Current groups "The Pfister Sisters" and "Boswellmania" continue to imitate the sister's recordings.
