Perkeo of Heidelberg (born Clemens Pankert, according to other sources Giovanni Clementi; 1702–1735) was a jester and court dwarf of Elector Palatine Charles III Philip in Heidelberg. As guardian of the Great Heidelberg Tun, he has since become an unofficial mascot of the city and region. His name, story and image have been connected with a variety of festivals, traditional songs, cultural and scientific institutions, hotels, restaurants and private companies (in and out of the region) ever since.
