The Golestan Palace (Persian: کاخ گلستان, Kākh-e Golestān), also transliterated as the Gulistan Palace and sometimes translated as the Rose Garden Palace from Persian language, was built in the 16th century, renovated in the 18th century and finally rebuilt in 1865. It is the former official royal Qajar complex in Tehran.

One of the oldest historic monuments in the city of Tehran, and a UNESCO World Heritage Site, the Golestan Palace belongs to a group of royal buildings that were once enclosed within the mud-thatched walls of Tehran's arg ("citadel"). It consists of gardens, royal buildings, and collections of Iranian crafts and European gifts from the 18th and 19th centuries.

The origin of the Tehran's royal citadel can be traced back to July 6, 1404; when Ruy González de Clavijo, the envoy of Enrique III, traveled to Samarkand to meet with Timur, and he chose to stay at the house of Baba Sheikh (one of the elders of Tehran). It is believed that his house was located in the area of the royal citadel and later they were transformed into new buildings with changes. The beginning of the royal citadel can be traced back to the time of Suleiman I, with the construction of a palace in the Chenaristan area, a Divankhane where Soltan Hoseyn in the last year of his reign meet with the Ottoman government's ambassador, Ahmad Dari Effendi. Tehran's arg ("citadel") was built during the reign of Tahmasp I (r. 1524–1576) of the Safavid dynasty (1502–1736). Abbas the Great built a large garden in the northern part of the fence, which was later surrounded by a high wall and buildings were built, with the royal residence was built inside it. At the end of the Safavid era, Tehran was sometimes the temporary seat of the court of Safavid kings. The palace was later renovated by Karim Khan of the Zand dynasty (r. 1750–1779). Agha Mohammad Khan of the Qajar dynasty (1742–1797) chose Tehran as his capital. The arg became the seat of the Qajars (1794–1925). The court and palace of Golestan became the official residence of the Qajar dynasty. The palace was rebuilt to its current form in 1865 by Haji Ab ol Hasan Mimar Navai.

During the Pahlavi era (1925–1979), the Golestan Palace was used for formal receptions. The Pahlavi dynasty built their own palaces in the Niavaran and Sa'dabad palace complexes. The most important ceremonies held in the palace during the Pahlavi era were the coronations of Reza Shah in 1926 and Mohammad Reza Shah and Shahbanu Farah in 1967. In between 1925 and 1945, a large portion of the buildings of the complex were destroyed by the order of Reza Shah. He believed that centuries-old Qajar palaces should not hinder the growth of a modern city. In the place of the old buildings, commercial buildings with the modern style of 1950s and 1960s were erected.

The Golestan Palace Complex consists of 17 structures, including palaces, museums, and halls. Almost all of this complex was built during the 131 year rule of the Qajar dynasty. These palaces were used for many occasions such as coronations and other important celebrations. It also consists of three main archives, including the photographic archive, the library of manuscripts, and the archive of documents.

This terrace, known as the Marble Throne, was built in 1747-1751.

Dating back to 1759, this building was a part of the interior residence of Karim Khan of the Zand dynasty. The basic structure of the Karim Khani Nook is similar to the Marble Throne. Like the latter, it is a terrace. There is a small marble throne inside the terrace. The structure is much smaller than the Marble Throne and it has much less ornamentation. There was once a small pond with a fountain in the middle of this terrace. Water from a subterranean stream (the shah's qanat) flowed from the fountain into the pond and was later used to irrigate the palace grounds.

Naser al-Din Shah Qajar was fond of this corner of the Golestan Palace.

The Pond House was used as a summer chamber during the Qajar era. Works of European painters presented to the Qajar court are housed there.

The Brilliant Hall was built by the order of Naser ed Din Shah. It is named so as it features brilliant mirror work done by Iranian artisans.

This building replaced the building of Narenjestan in the north of the Ivory Hall (Talar e Adj).

Ivory Hall is a large hall used as a dining room. It was decorated with some gifts presented to Naser ed Din Shah by European monarchs.

The Mirror Hall is a relatively small hall designed by Haj Abd ol Hossein Memar Bashi (Sanie ol Molk).

The Salam ("Reception") Hall was originally designed to be a museum.

The Diamond Hall is located in the southern wing of the Golestan Palace, next to the Windcatcher Mansion.
