Kettner (Czech feminine: Kettnerová) is a surname of German origin. It means 'chain maker', but there is a theory that the surname could be a Czechization of other German words – Kötner (i.e. 'cottager', 'small field owner'), or from Gärtner ('gardener'). Another theory suggests that the surname could refer to someone from a place called Ketten or Garten. Notable people with the surname include:
Johanna Sophia Kettner (1722–1802), German soldier Marie Kettnerová (1911–1998), Czech table tennis player Michelle Kettner (born 1973), Australian weightlifter Nils Kettner (1898–1967), Swedish equestrian Steve Kettner (born 1969), Australian weightlifter William Kettner (1864–1930), American Democratic politician Zdeněk Kettner (born 1974), Czech teacher, politician and MP
