False

Explanation:

An integral domain is a non-zero commutative ring with no zero divisors.

A field also requires any non-zero element to have a multiplicative inverse.

The very name "integral domain" comes from the archetypal example, namely the integers.

The integers #ZZ# are not a field, since there are non-zero elements which have no multiplicative inverse.
