Charles Ansell (1752 – 1813) was an English miniature painter. He specialized in creating small-scale portraits, primarily using watercolour and enamel on ivory, a popular medium for miniatures during the late 18th and early 19th centuries.
Ansell exhibited his works at the Royal Academy of Arts in London over a significant period, from 1780 until 1812, showcasing his consistency and recognition within the artistic community of his time. His subjects often included members of the gentry and notable individuals, reflecting the demand for personal portraits in the era before photography. His style was noted for its delicate detail and precise rendering of facial features and costume within the confined format of miniature painting. Examples of his work are held in various public and private collections, including the Victoria and Albert Museum in London.
