Andrew Jackson Beard (1849-1921) was an African-American inventor; Beard was inducted into the National Inventors Hall of Fame in Akron, Ohio for his contributions to rail transport coupler design.

Beard's design, documented in U.S. patent 594,059, awarded November 23 1897, is sometimes cited as the first successful "knuckle" type coupler, but his design is an improvement on an earlier patent (U.S. patent 138,405) awarded to Eli H. Janney in 1873.
