王球（393年－441年），字倩玉，琅邪临沂（今山东临沂）人。王球是东晋司徒王谧的儿子，在宋官至尚书仆射。

王球年轻就与堂兄王惠齐名，仪容举止皆获称美。王球初除著作佐郎，但他不拜官。不久，除琅邪王司马德文的大司马行参军，后转主簿，又转时为豫章公世子的刘义符的中军功曹。义熙十四年（418年），刘裕封宋公，以十郡建宋国，王球拜世子中舍人。永初元年（320年），刘裕篡晋，王球任太子中舍人，后改任宜都王友，又转当其咨议参军，但因病离职。

元嘉四年（325年），王球获授义兴太守，因其时堂兄王弘正担任其上司扬州刺史，制度上五服内的亲属不能互相监督，故加王球宣威将军号。而王球在郡都有宽容简惠的美称。后历转太子右衞率，又入朝当侍中，领冠军将军及本州大中正。后转中书令，仍领侍中。

The globus cruciger (Latin, "cross-bearing orb"), also known as the orb and cross, an orb (Latin globus) topped (Latin gerere, to wear) by a cross (Latin crux), has been a Christian symbol of authority since the Middle Ages, used on coins, in iconography, and with the sceptre as royal regalia. The cross represents Christ's dominion over the orb of the world, literally held in the hand of an earthly ruler (or sometimes it is held by an angel). In the iconography of Western art, when Christ himself holds the globe, he is called Salvator Mundi, the Saviour of the World; his statue is the Infant Jesus of Prague.
