The chiton fauna of the Magellanic region is investigated based on material from various expeditions and collecting trips made between 1958 and 2003. In total, 15 species of chitons, including one probably undescribed species are recognized in this region. Among them, 14 species inhabit the Magellan Strait, Beagle Channel and Estados Island, and 11 species live near the Falkand Islands. Comparisons of these faunas reveal that the shallow water chiton fauna of the Falkland Islands is the most impoverished in the Magellan Strait. Eleven other species that were mentioned in the literature for the Magellanic region are discussed. Four brooding species were found with eggs and juveniles in their pallial grooves, and the brooding habit of Ischinochiton stramineus and Tonicia lebruni are reported for the first time.
