小威廉·兰比尔（William Laimbeer, Jr.，1957年5月19日－），美国前职业篮球运动员。兰比尔身高2米11(6呎11吋)，体重118公斤，场上司职中锋。兰比尔球风凶猛，以身为底特律活塞队“坏孩子”一代的头号打手而闻名。

兰比尔1979年进入NBA，在当年选秀中仅以第三轮总第69位被克里夫兰骑士队选中。当年骑士队并未与其签约，而是在其效力意大利职业俱乐部一年后方才吸收其入队。

1982年，兰比尔被交换到底特律活塞队，其后他一直效力于该队，直到退役。兰比尔粗野的球风使其广受批评，但是却赢得了底特律球迷的心。同队友伊塞亚·托马斯、乔·杜马斯、丹尼斯·罗德曼等人一道，兰比尔两次率队夺得NBA总冠军。他还曾4次入选全明星。
