大O符号(英語:Big O notation),又稱為漸進符號,是用于描述函数渐近行为的数学符号。更确切地说,它是用另一个(通常更简单的)函数来描述一个函数数量级的渐近上界。在数学中,它一般用来刻画被截断的无穷级数尤其是的剩余项;在计算机科学中,它在分析算法复杂性的方面非常有用。 大O符号是由德国数论学家保罗·巴赫曼在其1892年的著作《解析数论》(Analytische Zahlentheorie)首先引入的。而这个记号则是在另一位德国数论学家愛德蒙·蘭道的著作中才推广的,因此它有时又称为蘭道符号(Landau symbols)。代表“order of ...”(……阶)的大O,最初是一个大写希腊字母“Ο”(omicron),现今用的是大写拉丁字母“O”。
