球蟒（学名：Python regius）是蛇亚目蟒科蟒属下一种分布于非洲的无毒蟒蛇。

成球蟒的表鳞平滑，有两片肛鳞，雄蛇的肛鳞较大。

球蟒的体色以黑色为基调，背部有许多圆形斑纹。腹部呈白色或奶油色，有时会出现细碎的黑纹。不过一些特殊表现基因经过宠物商人的选育，使球蟒产生同种多形的情况，令球蟒的品系（斑纹或体色出现各种变异）数量大增。

The ball python (Python regius) is a python species found in sub-Saharan Africa. Like all other pythons, it is a non-venomous constrictor. This is the smallest of the African pythons and is popular in the pet trade, largely due to its typically docile temperament. No subspecies are currently recognized. It is also known as royal python. The name "ball python" refers to the animal's tendency to curl into a ball when stressed or frightened. The name royal python (from the Latin regius) comes from the fact that rulers in Africa would wear the python as jewelry.
