1959年12月21日,弗洛伦斯·格里菲斯·乔伊娜出生于洛杉矶南部一个有11个孩子的家庭中,其父是电力技师,其母为教师。1978年她高中毕业后在银行当职员并在田径教练鲍勃·克西手下训练,鲍勃发现她的短跑才能后,推荐她在洛杉矶大学攻读心理学,1983年获得了学位。1984年奥运会,她夺得200米银牌。1987年10月与厄尔·乔伊纳结婚,现有一个8岁女孩子。1988年美国奥运会选拔赛时,她创造了10秒49的女子百米世界纪录,这项纪录后来被许多专家所质疑,原因是比赛当天刮大风,女子百米比赛前后举行的所有项目均为超风速,而惟独女子百米的风速记录为0米/秒,这似乎不可能。乔伊娜在汉城预赛时就创造过百米10秒88的奥运会纪录,决赛时在超风速下,以10秒54夺冠;200米也创造了21秒34的世界纪录。除两项短跑外,4×100米接力又获第三枚金牌,4×400米接力获银牌。
