Maxillariinae is an orchid subtribe in the tribe Cymbidieae. It was formerly treated as the tribe Maxillarieae, and divided into a number of subtribes.
Generic boundaries in the tribe have changed substantially with new molecular evidence. Whitten et al. in 2007 included the following genera, some previously placed in the tribe Lycastinae, others in the subtribe Bifrenariinae. Some of these genera have subsequently been merged.
