Xixianykus (meaning "Xixia County Claw") is a genus of alvarezsauroid from the Late Cretaceous Period of China. Like most alvarezsauroids, it was a maniraptoran. It was found in the Xixia County and was described in 2010 by Xu Xing. It could be considered as cursorial, meaning it had a running lifestyle. It was only 50 centimeters long.
