Mudou Island is located 7 kilometers north of Jibeiyu. With a perimeter of 843 meters and an area of just 0.0244 square kilometers, it is a tiny islet best known for the Mudouyu Lighthouse. Other than lighthouse staff, there are no permanent residents on the island. Situated north of Jibeiyu, Mudou Island is the northernmost island of the Penghu archipelago. It was originally called "Modou Islet(墨斗嶼)" due to its resemblance to a carpenter's ink marker, as it is formed from a basalt mesa. Over time, the name evolved to "Mudou Island" due to pronunciation changes. Given its location at the northernmost point of the Penghu archipelago, it is also known as the "North Island(北島)."
