We report on the detection of diffuse radio emission in the X-ray luminousand massive galaxy cluster A1351 (z=0.322) using archival Very Large Array dataat 1.4 GHz. Given its central location, morphology, and Mpc-scale extent, weclassify the diffuse source as a giant radio halo. X-ray and weak lensingstudies show A1351 to be a system undergoing a major merger. The halo isassociated with the most massive substructure. The presence of this source isexplained assuming that merger-driven turbulence may re-accelerate high-energyparticles in the intracluster medium and generate diffuse radio emission on thecluster scale. The position of A1351 in the logP$_{1.4 GHz}$ - logL$_{X}$ planeis consistent with that of all other radio-halo clusters known to date,supporting a causal connection between the unrelaxed dynamical state of massive($>10^{15} M_{\odot}$) clusters and the presence of giant radio halos.
