Hiroshima Peace Memorial Park (広島平和記念公園, Hiroshima heiwa kinen kōen^?) is a memorial park in the center of Hiroshima, Japan. It is dedicated to the legacy of Hiroshima as the first city in the world to suffer a nuclear attack, and to the memories of the bomb's direct and indirect victims (of whom there may have been as many as 140,000).

The location of Hiroshima Peace Memorial Park was once the city’s busiest downtown commercial and residential district. The park was built on open field that was created by the explosion. Today there are a number of memorials and monuments, museums, and lecture halls, which draw over a million visitors annually. The annual 6 August Peace Memorial Ceremony, which is sponsored by the city of Hiroshima, is also held in the park. The purpose of the Peace Memorial Park is to not only memorialize the victims, but also to establish the memory of nuclear horrors and advocate world peace.
