Captain Lewis Rendt (born 1769 in Germany, died 1849 in Canada) was an early 19th-century Hessian soldier of the Swiss Regiment, who later fought with the British in the Mediterranean (during the Invasion of Sicily), Spain, Egypt, and North America (during the British-American 1812 War). His regiment fought under the Duke of Wellington in Spain from 1811 to 1813. He was stationed variously at Cadiz, Malta, and Montreal.
