Tiliaceae /tɪliˈeɪsiː/ is a botanical name for a family of flowering plants. It is not a part of the APG, APG II and APG III classifications, being sunk in Malvaceae but has an extensive historical record of use. All through its existence the family has had a very lively history, with various authors taking very different views on what should be part of this family. As a result, it is recommended when this name is encountered to check what the author means. However, in the northern temperate regions the name is unambiguous as the only representative is Tilia, the lime or linden.
