14309 Defoy (A908 SA) is a Mars-crosser asteroid discovered on September 22, 1908, by Johann Palisa at Vienna. Joachim Schubart was involved in the identification also.[2] The number is very high for this time period, with the next numbered minor planet being 14310 Shuttleworth, discovered in 1966.[1]

Most of Palisa's discoveries were between 136 Austria (discovered 1874) and 1073 Gellivara (d. 1923), but this one had a much higher numbering.[3] Palisa worked from Vienna Observatory for this discovery.[3]

The asteroid is named for the woman Ilse Defoy.[2] The Defoy family were landowners near the city of Foy in modern-day Belgium.[2]
