前庭大腺，又称巴多林氏腺，简称巴氏腺（Bartholin's gland，日语：大前庭腺），在阴道口左、右两侧，约位于两侧大阴唇后部，腺管开口于小阴唇内侧靠近阴道前膜处。与男性的尿道球腺同源。

亢奋状态下，独立之腺体大小约呈现几厘米宽。前庭大腺通常会聚集在一起，会分泌一种无色、碱性、略黏稠的液体，以降低性行为过程中的摩擦。

该组织很容易感染淋菌与其他皮肤病变，其病灶来自外来细菌，症状则为堵住阴道口或尿道口，并会产生化脓、红肿与疼痛。

The Bartholin's glands (also called Bartholin glands or greater vestibular glands) are two pea sized compound racemose glands located slightly posterior and to the left and right of the opening of the vagina. They secrete mucus to lubricate the vagina and are homologous to bulbourethral glands in males. However, while Bartholin's glands are located in the superficial perineal pouch in females, bulbourethral glands are located in the deep perineal pouch in males. Their duct length is 1.5 to 2.0 cm and open into navicular fossa. The ducts are paired and they open on the surface of the vulva.
