Lambert Lombard (c. 1505 – August 1566) was a Renaissance painter, architect and theorist for the Prince-Bishopric of Liège. During his career he worked for Jan Gossaert in Middelburg and trained Frans Floris.
Lombard was born in Liège, where in 1532 he became court painter and architect. A few paintings and many drawings have been preserved.
In 1537 he was sent to Rome by Erard de la Marck, prince-bishop of Liège, to buy works of art, and he discovered the wonders of the Italian Renaissance. On his return he brought not only works of art, but also the new ideas concerning art and the position of the artist, to Liège.
His pupils were Frans Floris, Hendrick Goltzius, Willem Key, Dominicus Lampsonius, Jan Ramey, and Lambert Suavius. Dominicus Lampsonius wrote a biography of Lombard, The Life of Lambert Lombard.
