Liliales is an order of monocotyledonous flowering plants in the Angiosperm Phylogeny Group and Angiosperm Phylogeny Web system, within the lilioid monocots. This order of necessity includes the family Liliaceae .

百合目（学名： Liliales ）是被子植物種系發生學組（APG）和被子植物種系發生網絡系統中的單子葉 開花植物的一個目，屬百合類單子葉植物。 不論系統，此目必然包括 百合科 。

Liliales, the lily order of monocotyledonous flowering plants, containing 11 families, 67 genera, and 1,558 species of largely perennial herbs and climbers. Members of this order are important as sources of food, in the production of drugs and chemicals, and especially as ornamental plants.

The lily family, Liliaceae, consists of about 15 genera and 610 species of flowering plants within the order Liliales. [2] They are monocotyledonous, perennial, herbaceous, often bulbous geophytes. Plants in this family have evolved with a fair amount of morphological diversity despite genetic similarity.

百合属（学名： Lilium ），是百合目 百合科的一属。 其下有100余种 [1] ，有时通称为百合花，均为多年生草本鳞茎 植物，主要自然分布于亞洲東部、歐洲、北美洲等北半球溫帶地區。. 百合属物种及人工杂交所培育的品种常被运用于切花及景观设计中，例如OT百合、東方型百合、玫瑰百合等。

The Liliales is a fairly large group of monocotyledons that include 10–11 families (Table 7.2; Figure 7.27). As with the Asparagales, family delimitations of the Liliales have undergone a number of changes in recent years. Only the Liliaceae are described here.

Liliales have by far the largest nuclear genomes in monocots, and also the greatest absolute spread in values - 1.5-152.2 pg (1C: Leitch & Leitch 2013). For chromosome size, see Vijayavalli and Mathew (1990 - as Liliaceae) and Tamura (1995).

百合目是被子植物下单子叶植物分支的一个目。该目由10个科组成，共67属，约1768种不同的物种。 百合目植物通常为多年生草本，具根状茎、鳞茎或球茎，少数为草质或木质藤本。
