PROBLEM TO BE SOLVED: To provide a vehicle door capable of improving the rigidity of a lower reinforcement member and suppressing the displacement of a beam extension portion of a door beam at a time of a side impact.SOLUTION: A vehicle door comprises: a door body 21; a lower reinforcement member 3 extending from a lower end of an interior of the door body 21 in a door width direction; and a door beam 4 that includes a beam extension portion 42 extending downward from a door body portion 41 extending in the door width direction. The lower reinforcement member 3 includes an upper surface 3a extending generally horizontally and a vehicle outer surface 3b extending downward from the upper surface 3a. The upper surface 3a includes trough portions 3c and crest portions 3d protruding upward from the trough portions 3c. The beam extension portion 42 includes an extension body 42a disposed to overlap the vehicle outer surface 3b from a vehicle outside in a view in vehicle inward/outward directions, and an inner extension portion 42b extending from the extension body 42a to a vehicle inner side above the trough portions 3c and disposed to overlap the crest portions 3d above the trough portions 3c in a view in the door width direction. |
