Not normally.

Explanation:

At standard temperatures and pressures, the standard state of water is as a liquid. At elevated temperatures, and low pressures, water can be gaseous; in fact, water always has a vapour pressure.

The answer to your question is thus NO. Sometimes, the behaviour of water vapour can approximate the behaviour of an ideal gas.
