Anderson Marcelo da Silva (born 23 January 1981 in Kaloré, Paraná), commonly known as Marcelão, is a Brazilian footballer. He last played for Inter de Limeira.

Marcelão played domestically with Mogi-Mirim, Londrina and Guarantinguetá (2000-2001). In April 2001 he left for FC Barcelona with Triguinho. This transfer was remarkable as Guarantinguetá is owned by "CSR Futebol e Marketing", an organization of former Brazilian international Rivaldo who played at FC Barcelona at the time. Marcelão was registered by FC Barcelona for the La Liga as a replacement for the long-term injured Abelardo Fernández, but the Brazilian ultimately did not play in the Spanish league. Marcelão did play two games in the Copa de Catalunya, on April 26, 2001 as a substitute against UDA Gramenet and on June 13, 2001 in the starting line-up in the final against CF Balaguer. In August 2001, he played against Derby County FC and Blackburn Rovers FC during a training camp in England. In both games, the defender was a substitute for Patrik Andersson: against Derby County he replaced the Swedish twenty minutes before the end and against Blackburn Rovers at half-time. In the season 2001/2002 Marcelão was sent on loan to Gimnàstic de Tarragona to play in the Segunda División.

Marcelão played for Oeste in 2004,^[1] and in 2005 for Marília.^[2] In 2007, while playing for Vila Nova, he was loaned to Brasiliense for the club's participation in that year's Copa do Brasil.^[3]

In 2007, he was transferred from Vila Nova to Boavista for the 2007-08 Portuguese season.^[4] Marcelão joined Greek club Asteras Tripolis in 2008.^[5]
