Lightning Bar was an American Quarter Horse racehorse and breeding stallion. He was owned by Art Pollard. Lightning Bar's father was a Thoroughbred, and his mother was originally from Louisiana. Louisiana was known for breeding racehorses that ran short distances. Although he only raced for one year, he still managed to achieve an AAA speed index. His racing career was cut short by illnesses. After racing, he became a show horse and a roping horse. As a breeding stallion, he only fathered eight crops of foals, but fathered a number of important horses. His most famous son was Doc Bar. Lightning Bar died in 1960 from disease, at the age of 9. Lightning Bar was inducted into the American Quarter Horse Association's (AQHA's) American Quarter Horse Hall of Fame in 2008.
