Robert Francis Jeaudoin was an American professional wrestler and civil engineer, also known by the ring name of "Hangman" Bobby Jaggers. Most of his renown as a wrestler came from his appearances in various National Wrestling Alliance-affiliated promotions.

In particular, he found his greatest success in Championship Wrestling from Florida and Pacific Northwest Wrestling, the latter near his hometown of Vancouver, Washington. His wrestling gimmick was of a cowboy from Kansas, where he spent the later years of his life. Debuting under the name "Bobby Mayne" (after his favorite wrestler Lonnie Mayne) in 1972 in the Pacific Northwest against Al Madril, Bobby Jaggers learned his craft.
