The basilar venous plexus (transverse or basilar sinus) is a venous plexus of dural venous sinuses situated upon the clivus and posterior aspect of the dorsum sellae of sphenoid bone.

[1] It communicates with the anterior vertebral venous plexus.

The basilar venous plexus can sometimes be involved in certain medical conditions, such as a posterior circulation infarction and a cavernous sinus thrombosis.
