Lucas de Heere (1534 – 29 August 1584) was a Flemish portrait painter, poet and writer.
De Heere, a Protestant, was born in Ghent, and became a refugee from the Dutch Revolt against Philip II of Spain, who tried to suppress Protestantism. De Heere had to flee to England, where he became an elder of the Dutch stranger church of Austin Friars. After the Pacification of Ghent in 1576 he was able to return home, if only for a while. He was once again forced to leave the city in 1584 when Ghent surrendered to Spanish Habsburg forces.
He was very popular during his career and became immensely rich. His portrait of Katheryn of Berain is held by the National Museum Cardiff. He painted a head of Philip II from the life in 1553, as a letter of Cardinal Granvelle documents; this is presumed to be the painting now in the Prado.
In England he trained other young Netherlanders: John de Critz, probably Marcus Gheeraerts the Younger, and possibly as well the English Robert Peake the Elder.
Some time between 1573 and 1575, working on-site, he painted Stonehenge - the sketch is now in the British Library, and is the earliest known realistic depiction of the site.
