Abstract: A two-dimensional analog of Levinson's theorem for nonrelativistic quantum mechanics is established, which relates the phase shift at threshold (zero momentum) for the $m$th partial wave to the total number of bound states with angular momentum $m\ensuremath{\Elzxh}$ $(m=0,1,2,\dots{})$ in an attractive central field.
