de Geest (16 August 1592 – c. 1661) was a Dutch Golden Age portrait painter from Friesland.

He learned painting from his father, Simon Juckesz, a stained glass worker.

In 1636 the Frenchman Charles Ogier, secretary to Cardinal Richelieu visited De Geest, to view his large collection of curiosities and coins.

Perhaps the most intimate portraits he painted were those of his direct family: De Geest influenced Jacob Adriaensz Backer, and his students were Jan Jansz.

His grandson Wybrand wrote plays, a travel guide to Rome, and published "Het Kabinet der Statuen" (1702).
