Yup... our very first (well, second if you count Earth) Class M planet... Gliese 581g.
About 20 light year away (only a couple thousand years at present technology level to get there...).
Being tidally locked (or nearly so) it doesn't sound like an ideal spot for colonization... but hey, if there IS liquid water, that'll be the first time it's ever been found outside our solar system.
