William Paul Modibo (born 18 May 1979) is a Cameroonian professional footballer who played as a central defender.
Born in Ngaoundéré, Modibo played the vast majority of his professional career in Portugal, his first stop being with C.D. Trofense in the third and fourth divisions. In 2006 he helped C.D. Aves promote to the Primeira Liga, only to be immediately relegated back.
After one season in Kuwait, Modibo returned to Portugal with Gil Vicente F.C. However, in the following transfer window, he moved clubs and countries again, signing with Beijing Guoan F.C. He started in most games during the campaign, helping the Chinese capital team win the national championship.
For 2010–11, aged 31, Modibo moved once again to Portugal, signing with modest F.C. Arouca in the second level.
