No, it is not automatic defrost. The vast majority of fridges this size are not. However, many small fridges, especially the tiny "cube" ones, build up a very thick layer of frost around the freezer compartment very quickly, such that they need to be manually defrosted every month or two. So far, at least for me, this fridge does not seem to have that problem, but obviously your results may vary depending on its setting and the humidity of where it's used.
