144 (one hundred [and] forty-four) is the natural number following 143 and preceding 145.

It represents a dozen dozens, or one gross. It is the number of square inches in a square foot.

In number theory, 144 is the twelfth Fibonacci number; it is the only Fibonacci number (other than 0, and 1) to also be a square.[1][2]
