Hylaeus hilaris is a species of bee, also known by the common name hilaris yellow-faced bee. It is endemic to Hawaii and known only from a single population. In September 2016, along with six other Hawaiian Hylaeus species, H. hilaris was listed for protection under the United States Endangered Species Act. This marked a first listing for any bee species in the US.
