Jonas Erikson Sundahl (1678-1762) was a Swedish-born architect who spent most of his working life at and around Zweibrücken in the German Palatinate.

In 1702, Gabriel Oxenstierna [sv], Charles' governor in Zweibrücken, asked for the services of an architect.

In 1715–1716, Sundahl designed and built a summer palace [de] for Stanisław at Zweibrücken, called Lustschloss Tschifflik,[3] overlooking the Schwarzbach.

From 1720 to 1725, Sundahl seems to have been chief architect (German: Baumeister [de]) to the court of Zweibrücken.

[2][Note 5] He was thereafter again chief architect at Zweibrücken, and was promoted to the rank of chamberlain (German: Hofkammerrat).

[2] In 1755, he resigned from his post (he was in his seventies), and was succeeded by his pupil and assistant Christian Ludwig Hautt [de] (1726-1806).

On 11 November 1705, Sundahl married Anna Dorothea von Bein (1680-1726), of a patrician family of Frankfurt am Main.
