George Lowther (died 1723) was an English pirate who, although little is known of his life, was reportedly active in the Caribbean and Atlantic during the early 18th century. His first mate was Edward Low.

Not much is known about him before becoming the second mate on the slave ship, Gambia Castle, which was under the command of Captain Charles Russell; however, Lowther was more popular with the crew, as Russell seemed to care more about his shipment of slaves than for his men. Russell distrusted Lowther, and when he attempted to have him flogged, many crew members took Lowther's side and defended him, causing a schism among the crew.

Also on board, after retreating from their fort, was a Captain Massey, along with a company of soldiers under his command. One night, while Captain Russell was offboard, Massey and Lowther decided to set sail without him. Massey intended to return to England, but Lowther, the crew, and Massey's own soldiers disagreed. Lowther was made captain and he renamed the Gambia Castle as Delivery. They attacked many ships but when Massey wanted to pillage a village on shore, he lost the vote as the risk was deemed too great. Lowther was able to obtain a smaller ship, named the Happy Delivery, and parted ways with Massey and his men.

Lowther left for the Carolinas, where he developed the tactic of ramming his ship into another, while his men boarded and looted it. Around 1721 he left for the Grand Caymans, where he ran into the Greyhound captained by Benjamin Edwards. Lowther gave a cannon shot for a signal. Greyhound responded with a broadside (simultaneous discharge of all cannons on a side of a ship). The pirates boarded the Greyhound, possibly killed the entire crew and burnt the ship. Lowther had many ships under his command by now, granting the 6-gun brigantine Rebecca to his lieutenant Edward Low, who left to begin his own pirate career and with whom Lowther and Francis Spriggs would briefly rejoin in late 1723.^[1] When Lowther sailed his fleet to Guatemala, they were attacked by natives, and he was forced to leave some ships and men behind. His crew and supplies were all transferred to the Revenge.

In 1722 he sailed to a secluded island called Blanquilla. However, before landing he was spotted by Walter Moore, commander of HMS Eagle. Lowther was able to escape to the island by slipping out of his cabin window, along with a dozen crewmen; only four made it to shore. After an extensive search Lowther's body was found. He had shot himself in the head rather than be taken prisoner.

The Post-Boy newspaper dated 2 May 1724 suggested that Lowther may have escaped. The newspaper reports:

The last Letters from S. Christopher bring Advice, that on the 20th of February, the Eagle Sloop, h ted out from that Island, had brought in thither the Pyrate Sloop she had taken from Lowther, with twenty of the Men that were on board, (Lowther himself and many of the Crew having made their Escape) and it was believed that twelve or thirteen of them would be convicted of Pyracy, and that the others would be clear’d, as being forced into the said Pyrates Service.

The same information is in Newcastle Courant newspaper dated 1 February 1724:

We have the good News from St. Christophers, that Captain Moor of the Eagle Sloop, discovering a Pyrate Sloop of 10 Guns, and 40 Men, commanded by Lowther, careening at the Island of Blanco, boarded, and took her, with 24 of her Men, but Lowther, and 10 more, jump'd over board, and escap'd, however 4 of them were afterwards taken by a Spanish Cannoe, and 'tis hoped Lowther and the Rest would be also taken.

The Daily Courant of June 12, 1724, reported that "The Master of the Eagle was afterwards informed, that George Lowther, the Captain of the said Pyrate Sloop, had shot himself on the said Island of Blanko, and was found dead with his Pistol burst by his Side."^[2]
