Benjamin Franklin Stringfellow (September 3, 1816 – April 26, 1891) was a pro-slavery border ruffian in Kansas, when the slavery issue was put to a local vote in 1855 under the Popular Sovereignty provision.

The Stringfellow brothers also stumped western Missouri organizing "blue lodges" along the entire Kansas border.

The brothers, working with David Rice Atchison, attempted to get residents of Southern states to move to Kansas with their slaves to counter settlements by the anti-slavery Massachusetts Emigrant Aid Company.

In 1859 after Kansas entered as a free state, Stringfellow moved to Atchison (named for his ally, political boss and future U.S.

Senator David Rice Atchison), where he continued to practice law, although his brother John temporary returned to Virginia to settle their father's estate.
