斯珀西波斯（Speusippus，－前338年）是位古希腊哲学家。前347年柏拉图去世后，斯珀西波斯成为希腊学园（前387年创建）的继承者。

他居住在那八年之久，并以过着放荡浪费的生活闻名。柏拉图本试图遏止他的恶习，但并没成功。后来其是死于自杀或是某种慢性萎缩病。

他认为没有意识到其他所有的知识要懂得每件事物是不可能的，反对怀疑主义。

虽然其支持柏拉图的论述，但根据希腊作家第欧根尼·拉尔修的记载，他反对柏拉图理论的形式。

Speusippus (/spjuːˈsɪpəs/; Greek:Σπεύσιππος; c. 408 – 339/8 BC) was an ancient Greek philosopher. Speusippus was Plato's nephew by his sister Potone. After Plato's death, Speusippus inherited the Academy and remained its head for the next eight years. However, following a stroke, he passed the chair to Xenocrates. Although the successor to Plato in the Academy, he frequently diverged from Plato's teachings. He rejected Plato's Theory of Forms, and whereas Plato had identified the Good with the ultimate principle, Speusippus maintained that the Good was merely secondary. He also argued that it is impossible to have satisfactory knowledge of any thing without knowing all the differences by which it is separated from everything else.
