The White-sided Hillstar (Oreotrochilus leucopleurus) is a species of hummingbird in the Trochilidae family. It is the southernmost species of hillstar, being found in grassland and scrub at altitudes of 1,200 to 4,000 metres (3,900 to 13,000 ft) in far southern Bolivia, Chile and western Argentina. It resembles the Andean Hillstar, but the male of that species has a far narrower brown (not black) line to the central belly.
