Václav Kosmák (September 5, 1843 - March 15, 1898) was a Czech novelist.
Kosmák was a priest as well as a writer.
Notable for his realism and humor, Kosmák's short stories sketch the provincial life of Moravia.
His collected works were published in 1883-1884; a second, more complete edition was published after his death.
Notable of his works include "Kukatko and Kukatek", "Jak Martin Chlubil Bloudil A Na Pravou Destu Opet Se Vratil" and "Pokoj Lidem Dobre Rule".
The Roman Catholic church where he was a priest, in Martinkov, outside of Prague, bears a monument in remembrance of his contribution to church, community, and the public.
His writings were until recently required reading in many Czech schools.
