One may occur when the moon is full.

A Lunar eclipse happens when the sun moon and earth are all lined up, with earth in between the sun and the moon. At this position, with the sun behind us and the moon in front of us, we see a full moon, as the light is reflected back of the surface. The lunar eclipse happens when the earths shadow can be seen on the moon.

We don't always get a Lunar eclipse when there is a full moon though, as we don't often get a perfect enough line up. This is due to the orbits of the Earth and moon not being perfectly flat.
