Loganiaceae are a family of flowering plants, belonging to order Gentianales. The family includes 13 genera, distributed around the world's tropics.

Earlier treatments of the family have included up to 29 genera. Some classification schemes, notably Takhtajan's, break the Loganiaceae as described here into as many as four families: Strychnaceae, Antoniaceae, Spigeliaceae and Loganiaceae. Recent DNA studies of the Gentianales have found strong support for Loganiaceae as a monophyletic clade containing 13 genera.
