Neither aliens nor alien spacecraft are known and proven to exist. In that sense, the answer is no. UFO means "unidentified flying object", not "alien spacecraft".
If there are aliens out there on other planets, and they see something they themselves cannot identify up in the air, then in that sense there is an alien UFO.
