Jan Ensing, or Ensingh (10 March 1819 — 19 December 1894) was a Dutch painter, graphic artist, and lithographer; primarily known for his portraits.

Engsing was born on 10 March 1819 in Groningen to Jan Ensing (1797–1867), a shopkeeper and merchant, and his wife, Geertje (née Kuipers).

In 1840, his painting of a taproom at a village inn won an award from "Pictura [nl]", a visual arts society.

In 1854, he was commissioned to paint the portraits of nineteen professors at the University of Groningen, to celebrate the opening of their new Academy Building.

This was the beginning of a larger portrait gallery, which is now housed in the Senate Chamber of the current Academy Building (a replacement for the earlier one, which was destroyed by a fire in 1906).
