Johann Gottlieb Rall (ca. 1726 - December 26, 1776 ) was a German colonel in command of Hessian troops in Trenton, New Jersey.

Early life and career
Rall was probably born as a so-called "soldier child" ca. 1725. He was a son of Captain Joachim Rall from Stralsund, who served in the regiment of Major General Donop. The first mention of Johann Rall was as a new cadet of the same regiment on 1 March 1740, commanded at this time by Colonel Prince Casimir von Isenburg of Isenburg-Birstein.
He was promoted to warrant officer on 25 July 1741; to second lieutenant on 28 August 1745; and to captain on 10 May 1753. Rall was promoted to major on 7 May 1760, under Major General Bischhausen and transferred, in January 1763, into the Stein garrison regiment, where he was appointed lieutenant colonel. On 22 April 1771, he was transferred to the Mansbach Infantry Regiment as a colonel. He became commander of the regiment in January 1772.
During this time, Rall fought in the War of the Austrian Succession and participated in campaigns in Bavaria, on the Rhine, in the Netherlands, and served in Scotland. He fought in the Seven Years' War (also called the French and Indian War) and was involved in many battles. From September 1771 until August 1772, he was in Russia and fought for Catherine the Great under Count Orlov in the Fourth Russo-Turkish War.
