Long Boi was an unusually tall male duck that lived by Derwent College, University of York, England. He was thought to be an Indian Runner duck-Mallard cross, standing out among the other ducks on the campus due to his height. He went viral and became an internet meme in 2021. His popularity saw him become an unofficial mascot for the university. At least one commentator has branded him 'Britain's most famous duck'.
