Johann (Kaspar) Benedikt Beckenkamp (1747–1828) was a German painter.
He studied under his father, Lorenz Beckenkamp and Jan Zick, at Koblenz.
At first, he devoted himself to painting landscapes, after C. G. Schütz; but later changed to portraiture.
He settled at Cologne, and successfully imitated the style of painting of the old German masters.
[1] For the church of St Maria Lyskirchen in Cologne, he painted a copy of a triptych with a central panel of the Pietà by Joos van Cleve, the original of which (now in the Städelsches Kunstinstitut in Frankfurt) had been sold a few years before.
