Stecherův mlýn, Historical watermill in Litvínovice, Czech Republic.

Stecherův mlýn is an isolated complex of several buildings on the left bank of a Vltava arm in Litvínovice, 0.5 km from the built-up edge of České Budějovice. The current buildings date from an 1858 rebuild after a fire. Two Jonval turbines, later replaced by a Francis turbine in 1918, were fed by a millrace from the Rožnov weir.

The site originally operated as a fulling mill in the 18th century before Vojtěch Lanna purchased it in 1837 and converted it into a sawmill. It later evolved into a production facility for oak parquet flooring that served major European buildings.

The mill is named after Antonín František Stecher, who bought the sawmill in 1915 and converted it into a flour mill; his family had run a colonial goods wholesale and bookshop in České Budějovice since 1899. His son-in-law, teacher Jaroslav Maňák, kept a summer flat here and ran the weather station with trained mill staff.

The mill is a private complex in Litvínovice, about 0.5 km from the southwestern edge of České Budějovice, on the left-bank arm of the Vltava. It is not open as a visitor site, so the buildings are seen from the outside; the former station site is a lawn 28 m from the mill building and 5 m from the millrace.

A meteorological station on the grounds recorded an extreme temperature reading that stands as a national record. The measurements from this station reflect the harsh climate conditions that can occur in this region.
