崖豆藤屬（學名：_Millettia_），是豆科蝶形花亞科下的一個屬，為喬木或灌木植物。該屬共有約 150 種，分布於熱帶和亞熱帶地區，例如牛大力（又稱「美麗崖豆藤」；Snowy Millettia）。

屬名 _Millettia_ 為紀念 18 世紀法國植物學家 J. A. Millett 而命名。

Hu 等人（2000 年）指出崖豆藤屬是一個高度異質性的屬，在 Dunn (1912) 承認的 16 個組中，4 個組隨後被其他學者提升為屬：白花組 (Millettia sect. Albiflorae Dunn)、小苞組 (M. sect. Bracteatae Dunn) 分別被 Geesink (1984) 處理為白崖豆屬 (_Imbralyx_ R. Geesink) 和內翅豆屬 (_Endosamara_ R. Geesink)；澳洲組 (M. sect. Austromillettia Dunn) 被 Compton (2019) 提升為澳腰豆屬 (_Austrocallerya_ R. Geesink)；Compton (2019) 將寬序組 (M. sect. Eurybotrtae Dunn) 分為 3 個屬：雞血藤屬 (_Callerya_ Endl.)、南海藤屬 (_Nanhaia_ J. Compton & Schrire) 和夏藤屬 (_Wisteriopsis_ J. Compton & Schrire)。白崖豆屬被置於刀豆氨酸群 (canavanine group) 中，與多數崖豆藤屬物種不同，後五屬現屬於紫藤族 (Tr. Wisterieae X. Y. Zhu)，與崖豆藤族演化關係甚遠。



用途

水黃皮（_Millettia pinnata_）的種子可供榨油，油含量約為重量的 25%，在印度為生物柴油的原料。
