The　problem　of　magnetohydrodynamic　(MHD)　mixed　convection　flow　near　a　stagnation-point　region　over　a　nonlinear　stretching　sheet　with　velocity　slip　and　prescribed　surface　heat　flux　is　investigated;　this　has　not　been　studied　before.　Using　a　similarity　transformation,　the　governing　equations　are　transformed　into　a　system　of　ordinary　differential　equations,　and　then　are　solved　by　employing　a　homotopy　analysis　method.　The　effects　of　the　nonlinearity　parameter,　the　magnetic　field,　mixed　convection,　suction/　injection,　and　the　boundary　slip　on　the　velocity　and　temperature　profile　are　analyzed　and　discussed.　The　results　reveal　that　the　increasing　exponent　of　the　power-law　stretching　velocity　increases　the　heat　transfer　rate　at　the　surface.　It　is　also　found　that　the　velocity　slip　and　magnetic　field　increase　the　heat　transfer　rate　when　the　free　stream　velocity　exceeds　the　stretching　velocity,　i.e.　epsilon　＜　1,　and　they　suppress　the　heat　transfer　rate　for　epsilon　＞　1.
