Yes! Multiple actually. That is if by "like planet earth" you mean habitable. NASA's spacecraft Kepler has discovered 1,000 possible habitable planets, and I believe 2 planets that are definitely habitable. One of the names is Kepler-22b.

Well... How much like Earth do you want it to be?
We really haven't seen anything that is ''just like Earth'' (as a previous question asked - - after which, the questioner backpedaled and got belligerant in telling those that answered she really only meant ''like Earth - not *exactly* like Earth'' - despite the answers that responded stating ''just like Earth'' and informed her that we hadn't found anything of that nature yet...)
We (or I should say, astronomers) have found a few planets that might be in a good zone for possible life-similar-to-as-we-know-it. IOW, temperate enough for water to exist as a liquid, not just ice or steam. And small enough to have reasonable gravity.
No 'little green men'. Or Wookies. Or Mangalores.
Perhaps some 'little green spores'.

yes.. but its so far from earth
1 of them was the size of earth
and some they believe they have liquid water for it's position from the mother star
