Caspar Fincke (1584 – 9 February 1655) was a Bohemian-Danish court smith during the reigns of Christian IV and Frederick III.
He has created some of the finest decorative metalwork for some of the most prominent buildings of the time, including Frederiksborg Castle, Kronborg Castle Christian IV's Chapel in Roskilde Cathedral and a number of churches around the country.
By 1618–18, he had already created his elaborate wrought iron gate for Christian IV's Chapel in Roskilde Cathedral.
The railing on the observation platform of the Round Tower in Copenhagen is also attributed to him.
In 1650, Frederick III appointed his son Morten Finckas his successor.
