《天虹（粤语版）》是由李添胜执导，谢贤,汪明荃,谭咏麟主演的港台剧。该电视剧于1979年在香港上映。俞淑宽早年丧夫，生下一女名任霭华。丧夫后她专心发展时装公司，成为时装界的顶尖儿人物，当霭华十岁的时候，她再嫁警司康世雄，引起家翁与女儿的不满。霭华从英国学成时装设计返港，决心要和母亲在时装界一较长短，但却尝到失败的滋味，幸得任职警界的男友于柏端时加安慰。淑宽事业上的死对头，梁沛怡为打击淑宽，趁霭华在事业低潮时，就将她罗致到自己的公司，与淑宽的公司竞争。这时，曾为贩毒集团主脑的屠日天改行任一时装公司经理，他很欣赏沛怡的干劲，决定拉拢沛怡加盟自己的公司，令霭华与沛怡在时装界也成为了竞争对手。在这个阶段，霭华不但在时装界崭露头角，而且亦和柏端恋爱成熟，宣布结婚。柏端的上司康世雄表面是正人君子，背后则受贿贪污，并与走私贩毒的日天勾结，更怀疑为人正直的柏端是廉署的卧底。就在柏端要和蔼华举行婚礼的前数天，柏端突然暴毙。霭华相信他是被人谋杀，于是和柏端生前另一位年青律师好友韦政立联手，展开一连串抽丝剥茧的调查，揭发了出人意表的重重黑幕。
