《逆缘》（英语：Daddy Cool），香港电视广播有限公司拍摄制作的穿越悬疑、人性、恩仇电视剧；由黎耀祥、姜大卫、陈家乐、夏文汐、林夏薇及黎诺懿领衔主演，并由黄山怡、陈山聪及江欣燕联合主演。编审刘枝华、雷秀莲，监制王心慰。
此剧为2018无线节目巡礼13部剧集之一。
故事以日战时期（即1940年代，主要是731事件）作背景，30岁游击队成员贺定国（陈家乐饰）被日军冷冻长埋实验室，七十三年后于意外中被解冻苏醒。定国千辛万苦终于在2018年找到年届73岁的儿子贺和平（姜大卫饰）及47岁的孙儿贺永年 （黎耀祥饰），却发现贺和平为人狡猾，骗取综援；贺永年则迷信风水命理，贪钱成性。贺定国惟有力挽狂澜，希望将子孙拉回正途。 与此同时，贺定国被政府安排到社署工作，结识了中日混血儿庄司晨（林夏薇饰），更冲破矛盾相恋。神秘富豪翁芷荞（夏文汐饰）恋上暖男才俊汤泽澄（黎诺懿饰） ，却牵涉在汤泽澄的谋杀官司，为摆脱罪名，聘请已成为著名玄学家的贺永年摆风水阵作法。贺永年财迷心窍，罔顾是非黑白，种下祸根，更牵连到贺和平及贺定国，卷入另一宗谋杀案，一切不幸的事也从此刻开始，灾祸也陆续有来的一一来临...
此剧与《迷》一样，剧集初期也带有少量喜剧成分，但事实上此剧所谓的“温情家庭剧”同样只是宣传包装，实际上此剧本质也为悬疑及恩仇剧，尤其在剧集后半部分也能反映出剧集本质的悬疑及人性斗争的元素。且两部的监制都是王心慰。
