We report on the observation of the previously unknown isotope *2*1Al, the first unbound aluminum isotope located beyond the proton dripline. The *2*1Al nucleus decays by one-proton (1p) emission, and its in-flight decays were detected by tracking trajectories of the decay products with silicon microstrip detectors. The 1p-emission processes were studied by analyzing the measured angular correlations of decay products *2*0Mg +p. The 1p-decay energies of the ground and low-lying excited states of *2*1Al, its mass excess, and the proton separation energy value Sp = −1.15&sup(+0.10)&sub(−0.07) MeV were determined.
