Silent Hill 4: The Room is a 2004 survival horror game developed by Team Silent, a group in Konami Computer Entertainment Tokyo, and published by Konami. The fourth installment in the Silent Hill series, the game was released in Japan in June and in North America and Europe in September. Silent Hill 4 was released for the PlayStation 2, Xbox, and Windows. Its soundtrack was released at the same time. In 2012, it was released on the Japanese PlayStation Network. On October 2, 2020, it was re-released on GOG.com with patches to make it playable on Windows 10.

Unlike the previous installments, which were set primarily in the town of Silent Hill, this game is set in the southern part of the fictional city of Ashfield, and follows Henry Townshend as he attempts to escape from his locked-down apartment. During the course of the game, Henry explores a series of supernatural worlds and finds himself in conflict with an undead serial killer named Walter Sullivan.

Silent Hill 4 features an altered gameplay style with third-person navigation and plot elements taken from previous installments. Upon its release, the game received generally favorable reviews from critics, but its departure from the traditional formula of the previous games proved to be divisive. However, the game did receive praise for implementing some unique gameplay mechanics like the hauntings within the apartment.
