203 (two hundred [and] three) is the natural number following 202 and preceding 204.

In mathematics[edit]

203 is the seventh Bell number, giving the number of partitions of a set of size 6.[1] 203 different triangles can be made from three rods with integer lengths of at most 12, and 203 integer squares (not necessarily of unit size) can be found in a staircase-shaped polyomino formed by stacks of unit squares of heights ranging from 1 to 12.[2]
