We investigate the environments of post-starburst galaxies by measuring \\textsl{(1)} number densities in $8 h^{-1} \\mathrm{Mpc}$ radius comoving spheres, \\textsl{(2)} transverse distances to nearest Virgo-like galaxy clusters, and \\textsl{(3)} transverse distances to nearest luminous-galaxy neighbors. We compare the post-starburst galaxies to currently star-forming galaxies identified solely by A-star excess or $\\Halpha$ emission.
