Křtiny is a market town in Blansko District in the South Moravian Region of the Czech Republic.
It lies in the Drahany Highlands, on the boundary of the Moravian Karst Protected Landscape Area.
Its tributary, a brook named Zemanův žleb, supplies several small fishponds.
The first written mention of Křtiny is in a deed of Pope Gregory IX from 1237, when the village was owned by a women's monastery in Zábrdovice (today part of Brno).
In 1718, a Baroque pilgrim complex was created by the original project of Jan Santini Aichel, but was modified during construction and was never fully completed.
