A bleb is a large blister filled with serous fluid. Blebs can form on a number of tissues due to different pathologies, including frostbitten tissues and damaged cell membranes. In ophthalmology, blebs may be formed intentionally in the treatment of glaucoma.

A bleb can also be a cytoplasmic extension present during apoptosis. The formation process is called blebbing.
