Collocalia is a genus of swifts, containing some of the smaller species termed "swiftlets". Formerly a catch-all genus for these, a number of its former members are now normally (though not by all authors) placed in Aerodramus.

The genus Collocalia was introduced by the English zoologist George Robert Gray in 1854.{{ cite book | editor-last=Peters | editor-first=James Lee | editor-link=James L.

The genus previously contained fewer species. Seven subspecies of the glossy swiftlet were promoted to species status based on a detailed analysis of the swiftlets in the genus Collocalia published in 2017.{{ cite journal | last1=Rheindt | first1=Frank E. | last2=Christidis | first2=Les | last3=Norman | first3=Janette A. | last4=Eaton | first4=James A. | last5=Sadanandan | first5=Keren R. | last6=Schodde | first6=Richard | year=2017 | title=Speciation in Indo-Pacific swiftlets (Aves: Apodidae): integrating molecular and phenotypic data for a new provisional taxonomy of the Collocalia esculenta complex | journal=Zootaxa | volume=4250 | issue=5 | pages=401–433 | doi=10.11646/zootaxa.4250.5.1 | pmid=28609999 }}
