Muhammad Abu Bakar bin Mahari (born 11 February 1985) is a Bruneian footballer playing as a striker for Kota Ranger FC of the Brunei Super League.

Abu Bakar was sent on loan to his old club the Prisons Department while DPMM could not resume playing due to a FIFA ban[broken anchor].

[7] Contemplating retirement, his then-coach Vjeran Simunić finally convinced him to play for DPMM in their comeback season in 2012, but he only managed to appear in 4 games before being released.

[14] On 11 August, in a match that pitted two unbeaten teams in the Super League, Abu Bakar scored two goals to beat his club's direct rivals MS ABDB.

Abu Bakar's league form in 2017 forced the doors to an international callup in December for the 2017 Aceh World Solidarity Tsunami Cup, nine years after last representing his country.
