The analysis of mixed convection Casson fluid with the effect of porosity and radiation was conducted. The governing partial differential equations (PDE) in dimensional form were formulated with associated initial and boundary conditions. The PDE were transformed into dimensionless form by presenting suitable non-dimensional variables. The temperature and velocity profiles were obtained by employing the method of Laplace transform, to ensure that initial and boundary conditions involved were satisfied. The graphical representation illustrates the effects of parameters for Casson fluid, porous medium and Grashof (Gr) number, in addition to radiation. It is inferred that at the start, the velocity decreases. However, at some point the velocity rises when the Casson parameter increases. Additionally, the increasing of radiation and Grashof number has influenced the velocity to increase
