Osztopán (Croatian: Stupan) is a village in Somogy county, Hungary.
The name comes from the Slavic Stupan[2] [3] derived from the Proto-Slavic stem stǫp- with several meanings and possible etymologies (i.e. stǫpa/stupa: trapping pit,[2] see also the etymology of Stupava).
According to László Szita the settlement was completely Hungarian in the 18th century.[4]

The Hungarian folk song Osztopáni malomárok was collected in Osztopán in 1949 by Ferenc Gönczi.
