The pelvic cavity is a body cavity that is bounded by the bones of the pelvis and which primarily contains reproductive organs, the urinary bladder, and the rectum.

The boundaries are as follows:
- anterior: pubic symphysis
- posterior (or "roof"): piriformis, sacrum, coccyx
- lateral: obturator internus
- floor: levator ani muscle (or, more generally, the pelvic floor)
The lesser pelvis (or "true" pelvis" only includes structures inferior to the pelvic brim.
For example, the pelvic splanchnic nerves arising at S2-S4 is in the true pelvis, but the femoral nerve from L2-L4 is only in the "false pelvis", or greater pelvis.
