Guylian (French pronunciation: [ɡiljaːn]) is a Belgian chocolate manufacturer founded by Guy Foubert in 1960. The company takes its name from the combination of Foubert's first name (Guy) with that of his wife, Liliane. Guylian is perhaps most famous for their production of chocolate Sea Shellspraline with different fillings. Guylian has been the major sustaining sponsor of Project Seahorse since 1999.
In 2008, Lotte Confectionery from South Korea bought the company for $164 million.
