'''Gentianales''' are an order of [[flowering plant]]s, included within the [[asterid]] group of [[dicotyledon]]s.
The circumscription of Gentiales in the [[Cronquist system]] included a broadly defined [[Loganiaceae]] (since broken up into several families), [[Retziaceae]], [[Gentianaceae]], [[Saccifoliaceae]], [[Apocynaceae]], and [[Asclepiadaceae]]. The circumscription recognized by the [[Angiosperm Phylogeny Group]] (APG) includes Apocynaceae (including Asclepiadaceae), [[Gelsemiaceae]] (segregated from Loganiaceae), Gentianaceae (including Saccifoliaceae), Loganiaceae, and [[Rubiaceae]].
Under the APG definition some well-known members of Gentianales are [[coffee]], [[gardenia]]s, and [[frangipani]].
APG includes Retziaceae in [[Stilbaceae]] (order [[Lamiales]]).
