Joseph Wintergerst (3 October 1783, Wallerstein - 25 January 1867, Düsseldorf) was a German painter in the Romantic style; associated with the Nazarene movement.
He was born to the painter, Anton Wintergerst (1737–1805), and his second wife, Maria Barbara née Bux, daughter of the faience maker, Johann Baptist Bux (1716-1800).
In 1811, he went to Rome with his friends, Friedrich Overbeck and Franz Pforr, and joined the artists' colony at Sant’Isidoro a Capo le Case.
Pforr's untimely death in 1812 left him unsettled so, in 1813, he went to Switzerland, accompanied by Christian Xeller [de], and taught at the Cantonal school in Aarau.
Two years later, Wintergerst succeeded Peter's brother, Lambert Cornelius [de] as "Inspector" and began giving drawing lessons at the Royal Gymnasium [de].
