Leonard L. Amburgey (born 1945) is an American amateur astronomer, discoverer of minor planets and public-school teacher by profession.
On July 2, 2000, he stumbled upon the near-Earth and Apollo asteroid using a modest telescope in his backyard in Fitchburg, Massachusetts (IAU number 823). As a result, he became the fourth winner of the James Benson Prize for Discovery Methods of Near-Earth Objects by Amateurs.
In 2005, he received the Fitchburg State College (whence he graduated in 1968 and 1973) Alumni Achievement Award.
