George Wightwick Rendel (6 February 1833 – 9 October 1902) was an English engineer, and naval architect. He was closely associated with the Tyneside industrialist and armaments manufacturer, William George Armstrong. Family George was the third (of five) sons of the civil engineer James Meadows Rendel and his wife Catherine Harris. He was named after George Wightwick, a lifelong friend of his father. He was educated at Harrow, but ran away in 1849. His siblings included Alexander Meadows Rendel, Hamilton Owen Rendel and the Liberal MP Stuart Rendel, 1st Baron Rendel. George Rendel married firstly on 13 December 1860 Harriet Simpson, daughter of Joseph Simpson, the British vice-consul at Kronstadt. They had five sons before her death in 1878. He met his second wife, Lucinia Pinelli, in Rome, while serving on a design committee of the Italian Ministry of Marine. They married in 1880 and had three sons (Silvio Rendel, Florian Rendel and George Rendel) and a daughter. His youngest son went on to become the distinguished diplomat Sir George William Rendel.

He lived with Armstrong at his house in Jesmond for three years before completing his engineering education at his father's London office. His father died in 1856 and the brothers George, Stuart and Hamilton all joined Armstrong's company, while Alexander took over the family business.

George Rendel was one of three partners in the business, along with George Cruddas and Richard Lambert. Armstrong had been helped in his early career by James Rendel, and treated his son as a protégé. In 1864 the Elswick Ordnance Company was merged with Armstrong's original company to form Sir W G Armstrong and Company. George Rendel was one of seven partners in the new company, and was in joint charge of the ordnance departments, together with Captain
