Christian Vieri (Italian pronunciation: [ˈkristjaɱ ˈvjɛːri]; born 12 July 1973) is an Italian former professional footballer who played as a centre forward.

Vieri was named in the FIFA 100, a list of the 125 greatest living footballers selected by Pelé as a part of FIFA's centenary celebrations. For a number of years he was regarded as one of the finest strikers in Europe, leading to him becoming the world's most expensive player in 1999 when Inter paid Lazio £32 million (€43 million) for his services. Something of a footballing nomad, Vieri played for no fewer than 12 clubs throughout his career. Most notable were his successful spells at Juventus, Atlético Madrid, Lazio and Inter, clubs with which he won several honours.
