'''WASP-8b'''是一顆位於[[玉夫座]]的[[太陽系外行星]]。該行星由[[SuperWASP]]與其他行星（[[WASP-6b]] 到 [[WASP-15b]]）一起發現。2008年4月1日，[[贝尔法斯特女王大学]]的唐·波勒（Don Pollacco）在2008年的英國皇家天文學學會全國天文學會議（NAM 2008）宣布這項發現<ref name="announce">{{cite web<br />

該行星距離地球49秒差距，是 SuperWasp 計畫發現最接近地球的系外行星，比 [[HD 17156]] 和 [[HD 149026]] 更接近地球。它的密度高於木星。<br />
