The right lower lobe posterior or posterior basal segment is one of the five bronchopulmonary segments of the right lower lobe. It is the most inferoposterior of the segments in the right lower lobe, below the superior segment.

Due to its low and posterior position, pathology in the right lower lobe posterior segment can produce opacification that may only been present on the lateral chest radiograph at the posterior costophrenic angle.
