Stefan Lochner (Meersburg, 1400 – Cologne, 1452) is a German late Gothic painter.
He works in Cologne, Germany, and his principal work is a triptych known as the Altar of the City Patrons, painted for the Town Hall chapel in the 1440s and now in Cologne Cathedral.
It represents the city in homage to the infant Jesus.
His style, famous for its clean appearance, combines Gothic attention towards long flowing lines with brilliant colors with a Flemish influenced realism and attention to detail.
His compositions are often sprinkled with fanciful angels, singing and playing musical instruments.
