We investigate the muon anomalous magnetic moment in the context of the supersymmetric version of the economical 3-3-1 model. We compute the 1-loop contribution of super-partner particles. We show that the contribution of superparticle loops become significant when $\tan \gamma $ is large. We investigate for both small and large values of $\tan \gamma$. We find the region of the parameter space where the slepton masses are of a few hundreds GeV is favoured by the muon $g-2$ for small $\tan \gamma $ ($\tan \gamma \sim 5 $). Numerical estimation gives the mass of supersymmetric particle, the mass of gauginos $m_G \sim 700$ GeV and light slepton mass $m_{\tilde{L}}$ is of order $ \cal O$ (100) GeV. When $\tan{\gamma}$ is large ($\tan{\gamma} \sim 60$), the mass of charged slepton $m_{\tilde{L}}$ and the mass of gauginos $m_G$ $\sim$ $\cal O$(1) TeV while the mass of sneutrino $\sim 450$ GeV is in the reach of LHC.
