We are concerned with a three-dimensional layer of a perfect and irrotational liquid of density one (e.g. water) in a gravity field pointing vertically downwards. The layer is of infinite depth and bounded above by a free surface. Babenko developed a variational theory of steady periodic two-dimensional water waves without surface tension, and the aim of this paper is to extend Babenko's formulation to three-dimensional steady periodic waves.
