Tóth (sometimes Toth) is a very common surname in Hungary, meaning "Slav" and later "Slovak" in old Hungarian (now spelt tót).
It can also mean "Croat", since one of the Hungarian names for Slavonia (the northern part of Croatia, bordering to Hungary) was Tothorszag; although Horváth is the more usual contemporary formulation.
The surname Toth is also a less common German surname (Tod), which is a variation of the old German word for 'death'.
