Lambert Lombard (French pronunciation: [lɑ̃bɛʁ lɔ̃baʁ]; 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.

In 1537, he was sent to Rome by Érard de La Marck, prince-bishop of Liège, to buy works of art, and he discovered the wonders of the Italian Renaissance.

His pupils were Frans Floris, Hendrick Goltzius, Willem Key, Dominicus Lampsonius, Jean Ramey [fr], and Lambert Zutman [fr].
