A sealing structure for a vehicle door seals a gap between a door and body of the vehicle and includes a sealed portion as a gap between the body and a door inner pane. A body weather strip is mounted at a first side of a lateral most portion of the sealed portion along a rim of an opening portion of the body and seals the gap between the body and door. An upper weather strip is mounted at a second side of the lateral most portion of the sealed portion along a roof panel and seals gaps between the roof panel, body, and door. A door weather strip is mounted in the sealed portion between the body and upper weather strips to be spaced apart from the body and upper weather strips, extends along the rim of the opening portion, and seals the gap between the body and door.
