Ångström is a small lunar impact crater located on the border between Oceanus Procellarum to the west and Mare Imbrium to the east. To the south is a formation of mountains rising out of the mare named the Montes Harbinger. To the east are some wrinkle ridges named the Dorsum Bucher and Dorsa Argand. This crater is bowl-shaped, with a circular rim and inner walls that slope down to the small central floor. It has a higher albedo than the surrounding maria.<ref name=Bussey_Spudis_2004/> The crater halo is radar dark, indicating a lack of larger blocks among the fine ejecta.<ref name=Ghent_et_al_2005/>

Ångström crater is named after Anders Jonas Ångström,<ref name=Blue2007/> a Swedish physicist and one of the founders of the science of spectroscopy.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Ångström.<ref name=Bussey_Spudis_2004/>
