Based on first-principles calculations, we investigate the electronic structure and magnetic properties of bare and hydrogen-terminated AlN nanoribbons (NRs). When both Al and N edges are terminated by hydrogen, it exhibits a semiconducting behavior with a direct band gap of 2.76 eV. The H-terminations at the Al edge lead to a ferromagnetic (FM) ground state with a net magnetic moment of 
per unit cell, while the H-terminated N edge state exhibits an antiferromagnetic property. For bare AlNNRs, the half-metallic, semiconducting, or metallic characters are all obtained, dependent on spin alignments of Al and N edge states. These predicted diverse and tunable electronic properties endow AlNNRs potential applications in electronics and spintronics.
