A (2+1)-dimensional generalized KdV equation (ut+u3 ux+αuxxx)x+βuyy =0, α, β∈ R + is subjected to Lie’s classical method. Classification of its symmetry algebra into oneand two-dimensional subalgebras is carried out in order to facilitate its systematic reduction to (1+1) dimensional PDE and then to ODEs. A solution containing two arbitrary functions of time t is also determined.
