Jumbo (about Christmas 1860 - September 15, 1885), also known as Jumbo the Elephant and Jumbo the Circus Elephant, was a 19th-century male African bush elephant born in Sudan. Jumbo was exported to Jardin des Plantes, a zoo in Paris and then transferred in 1865 to London Zoo in England. Despite public protest, Jumbo was sold to P. T. Barnum, who took him to the United States for exhibition in March 1882. The giant elephant's name has spawned the common word, "jumbo", meaning large in size.

Jumbo died at a railway classification yard in Canada at St. Thomas, Ontario on September 15, 1885. In those days the circus crisscrossed North America by train. St. Thomas was the perfect place for a circus because many rail lines converged in St. Thomas in that day. Jumbo and the other animals had finished their performances for the night and, as they were being led to their box car, a train came roaring down the track. Jumbo was hit and mortally wounded, dying within minutes.  Barnum told the story that Tom Thumb, a young circus elephant was walking on the railroad tracks and Jumbo was attempting to lead him to safety. Barnum claimed that the locomotive hit and killed Tom Thumb before it derailed and hit Jumbo. However, other witnesses did not support Barnum's account. According to newspapers, the freight train hit Jumbo directly, killing him, while Tom Thumb suffered a broken leg.  Many metallic objects were found in the elephant's stomach, including English pennies, keys, rivets, and a police whistle.  Ever the showman, Barnum had portions of his star attraction separated, in order to have multiple sites attracting curious spectators. After touring with Barnum's circus, the skeleton was donated to the American Museum of Natural History in New York City, where it remains. The elephant's heart was sold to Cornell University. Jumbo's hide was stuffed by William J. Critchley and Carl Akeley, both of Ward's Natural Science, who stretched it during the mounting process; the mounted specimen traveled with Barnum's circus for two years.  Barnum eventually donated the stuffed Jumbo to Tufts University, where it was displayed at P.T. Barnum Hall there for many years. The hide was destroyed in a fire in April 1975. Ashes from that fire, which are believed to contain the elephant's remains, are kept in a 14-ounce Peter Pan Crunchy Peanut Butter jar in the office of the Tufts athletic director, while his taxidermied tail, removed during earlier renovations, resides in the holdings of the Tufts Digital Collections and Archives.
