'''TRAPPIST-1e'''，也称为'''2MASS J23062928-0502285 e'''，是一颗接近地球大小的类地系外行星，在[[超低温矮星]][[TRAPPIST-1]]周围的[[适居带]]内运行，距离地球大约40光年（12秒差距，3800000万亿公里，240000000百万英里），位于宝瓶座。这颗系外行星是通过[[凌日法]]发现的，其中测量了行星穿过其恒星前方时产生的变暗效应。

它是通过[[斯皮策太空望远镜]]的观测发现的围绕这颗恒星运行的七颗新系外行星之一。<ref name=Gillon-Triaud-etal-2017/><ref name=Gillon-Jehin-etal-2016/>在七个当中的三个（e、f和g）位于适居带内。<ref name=NASA-press-exopl-1419/><ref name=JPL-press-21422/>TRAPPIST-1e有着类似于地球的质量、半径、密度、重力、温度和恒星通量。<ref name=Grimm-Demory-etal-2018/><ref name=Delrez-2018/>它也被证实有一个致密的大气层，就像我们太阳系中的其他类地行星一样。<ref name=deWit-Wakeford-etal-2018/>

2018年11月，研究人员确定，在多行星系统的七颗系外行星中，TRAPPIST-1e是最有可能成为类地[[海洋行星]]的一颗，也是最值得进一步研究适居性的一颗。<ref name=eurekalert-2018-11-21/>根据适居系外行星目录，TRAPPIST-1e是迄今为止发现的最有可能适居的系外行星之一。<ref name=Arecibo-PHL-HabPlanCtlg/>
