This paper considered the problem of Casson nanofluid flow over a vertical plate with variable thermal conductivity and the effects of its thermo-physical properties. The governing partial differential equations were reduced to nonlinear coupled ordinary differential equations using similarity variables. The coupled nonlinear ordinary differential equations were solved numerically using shooting method with Runge-Kutta fourth order scheme and simulated using MATLAB. The obtained result showed that increasing magnetic field and Casson fluid led to a reduction in the skin friction coefficient, Nusselt number and Sherwood number. Similarly, as Prandtl number becomes large, the local skin friction coefficient, Nusselt and Sherwood numbers reduces respectively.
