Peripatric and peripatry are terms from biogeography, referring to organisms whose ranges are closely adjacent but do not overlap, being separated where these organisms do not occur – for example on an oceanic island compared to the mainland. Such organisms are usually closely related (e.g. sister species), their distribution being the result of peripatric speciation.
