Agnes Cathinka Wilhelmine Lunn (16 March 1850 – 12 December 1941) was a Danish painter and sculptor. Lunn's work focused on depictions of domestic animals, particularly Icelandic horses. She also produced landscape paintings and architectural studies. Her most notable sculptures include: Hamlette (bronze statuette, 1899), Two Swimming Horses (bronze statuette, 1906, David Collection), and Resting Cow (1913, the Museum at Sønderborg Castle).
During her career, Lunn advocated for greater recognition of women artists in Denmark. She was a signatory to the petition which led to the establishment of a women's art school at the Royal Danish Academy of Fine Arts and was the co-arranger of the 1895 Copenhagen Women's Exhibition. Like many female artists of her era, Lunn never married.
