*Corpus Callosum is a 2002 experimental Canadian film directed by Michael Snow. It won the Independent/Experimental Film and Video Award from the Los Angeles Film Critics Association Awards.

The corpus callosum (; Latin for "tough body"), also known as the callosal commissure, is a wide, flat bundle of neural fibers about 10 cm long beneath the cortex in the eutherian brain at the longitudinal fissure. It connects the left and right cerebral hemispheres and facilitates interhemispheric communication. It is the largest white matter structure in the brain, consisting of 200–250 million contralateral axonal projections.
