Jean De la Vallée (1620–March 12, 1696) was a French-born architect, who lived and worked in Sweden. He was the son of Simon De la Vallée , who was killed by a Swedish nobleman in 1642. The father had started the planning of the House of Knights in Stockholm, and in 1660 his son finished his father's work. Prior to this, Jean De la Vallée had planned two major churches in central Stockholm, Katarina kyrka in 1656 and Hedvig Eleonora kyrka in 1658.

He also worked on the commission of many noblemen. For Magnus Gabriel De la Gardie he planned the remodeling of the Karlberg Castle in the capital. Other notable examples of his work are the castle of Skokloster , the Palace of Bonde (now the seat of the Supreme Court) and the remodeling of the Palace of Wrangel (now the seat of Svea Hovrätt, the Svea Court of Appeal), both on Riddarholmen in central Stockholm.

In 1680 he was awarded the title "Royal and City Architect", and in 1692 he was knighted.
