Pieter Christoffel Wonder was a Dutch painter, active in England.
Wonder was largely self-taught, by making copies of the Old Masters, although between 1802 and 1804 he did attend classes at the Kunstakademie Düsseldorf. In 1807 he established the "Genootschap Kunstliefde [nl]" (Love of Art Society) in Utrecht together with other artists including Jan Kobell, and served as Director.

From 1823 to 1831, he worked in England, where he became well known as a portrait painter, but also painted some interior scenes and copies of works by Raphael.
