Umineko no Naku Koro ni (うみねこのなく頃に, Umineko no Naku Koro ni? lit. When Seagulls Cry) is a Japanese murder mystery dojin soft visual novel series produced by 07th Expansion. The first game in the series, Legend of the golden witch, was first released at Comiket 72 on August 17, 2007 playable on the PC; the game sold out in thirty minutes. The story focuses on a group of eighteen people on a secluded island for a period of two days, and the mysterious murders that befall most of the people. The goal of the game is to discern whether the murderer is human or of some other supernatural source. Umineko is the third title in the "When They Cry" series, preceded by Higurashi no Naku Koro ni and Higurashi no Naku Koro ni Kai. According to the original creator, Ryukishi07, the red Na (な) in the logo is an official part of the title.

Umineko no Naku Koro ni takes place in the year 1986 during the time frame of October 4 and October 5 on a secluded island named Rokkenjima. The head of a wealthy family named Kinzō Ushiromiya, who lives on and owns Rokkenjima, is near death, and eleven of his family members arrive on the island to discuss how Kinzō's assets will be divided once he is dead. Also on the island are five of Kinzō's servants, and his personal physician. After the eleven family members arrive, a typhoon traps them on the island and shortly after people start to get mysteriously murdered.
