The Pacific Star Building, also known as the Nauru Building is a 29-storey high-rise building in Makati, Metro Manila, Philippines. The building was built by the Republic of Nauru through its Nauru Phosphate Royalties Trust. The high-rise building is managed by Century Properties Group. An adjacent 6-storey low-rise office building, the Pacific Star Building Low Rise is also partially owned by the company and is part of the building complex. The Monterrey building of DMCI was demolished to give way to the construction of the building. The Pacific Star Building was the tallest building in the Philippines upon its completion until it was surpassed by Rufino Pacific Tower.
