Carlos Alexandre de Souza Silva (born 1 August 1986), commonly known as Carlão, is a Brazilian professional footballer who plays for Thai club Ubon UMT United as a striker.
Carlão was born in Duque de Caxias, Rio de Janeiro. On 28 April 2008 he signed a three-month contract with Duque de Caxias Futebol Clube for the rest of the Série B season, joining from São Cristóvão de Futebol e Regatas. On 11 February of the following year he was signed by U.D. Leiria in the Portuguese second division, wasting no time making an impact as he scored 11 goals in just twelve games to help his team return to the Primeira Liga after a one-year absence; this included four past S.C. Olhanense in a 5–1 home win, on 3 May.
Carlão only netted five times in his first full season, however, in 28 matches. In late December 2010, after being linked to fellow league side Sporting Clube de Portugal, he was sold to Kashima Antlers in the J1 League, and in July 2011 the Japanese club loaned him to Neuchâtel Xamax in Switzerland.
In early September 2011, still owned by Kashima, Carlão returned to Portugal and joined S.C. Braga.
On 9 January 2012, after having come on as a substitute for Édson Rivera in the 60th minute of an away fixture against S.C. Beira-Mar, he scored the 2–1 winner.
On 19 February 2014, after a brief spell with F.C. Paços de Ferreira, Carlão moved to China with Shijiazhuang Yongchan FC.
