Tikhon of Kaluga (died 16 June 1492) was a Russian Orthodox hegumen and saint.

He then moved to a forest near Medin in Kaluga, living in the hollow of an oak tree.

It was on that spot that he founded (and became the first hegumen of) a monastery dedicated to the Dormition of the Mother of God (and then to Tikhon himself after his death).

He is commemorated with a feast day on 16 June in the Eastern Orthodox Church.
