Leopold I of Lippe (2 December 1767 – 5 November 1802) was a Prince of Lippe.
Leopold I was born in Detmold the son of Simon August, Count of Lippe-Detmold (1727–1782), and his second wife, Princess Leopoldine of Anhalt-Dessau (1746–1769).
He received his education in Dessau, and when he reached 18 he went to study at the University of Leipzig. He succeeded his father as Count of Lippe-Detmold on his death on 1 May 1782, and remained Count until Lippe was raised to a Principality of the Holy Roman Empire in 1789.

He died in Detmold and was succeeded as Prince by his eldest son, who became Leopold II.
He was married to Pauline Christine of Anhalt-Bernburg (23 February 1769 – 29 December 1820), daughter of Frederick Albert, Prince of Anhalt-Bernburg, and Louise Albertine of Schleswig-Holstein, on 2 January 1796 in Ballenstedt. From the marriage he had two sons:
