Count Simon VII of Lippe (30 December 1587 at Brake Castle near Lemgo – 26 March 1627 in Detmold) was a ruler of the Reformed County of Lippe-Detmold.

He was the second-eldest son of Count Simon VI of Lippe and his wife Elizabeth of Schauenburg and Holstein.

After Bernard's untimely death in 1602, Simon returned to Brake, where his father introduced him systematically to the business of government.

Simon VII remained neutral during the Thirty Years' War, in an attempt to spare his small country as much as possible.

Simon VII married Countess Anna Catherine (1590-1622), daughter of John Louis I, Count of Nassau-Wiesbaden-Idstein, in 1607.
