巴比伦数字是古巴比伦人使用的数字，采用60进制。巴比伦数字出现于公元前3100年左右，为目前已知最早的位值制数字系统。

1-59的59个数字由两个符号( 表示一 ， 表示十)构成。 巴比伦数字系统没有表示0的符号。

Babylonian numerals were written in cuneiform, using a wedge-tipped reed stylus to make a mark on a soft clay tablet which would be exposed in the sun to harden to create a permanent record.

The Babylonians, who were famous for their astronomical observations and calculations (aided by their invention of the abacus), used a sexagesimal (base-60) positional numeral system inherited from either the Sumerian or the Eblaite civilizations. Neither of the predecessors was a positional system (having a convention for which ‘end’ of the numeral represented the units).
