The Macau Special Administrative Region,is one of the two special administrative regions of the People's Republic of China, the other being Hong Kong. Macau lies on the western side of the Pearl River Delta, bordering Guangdong province in the north and facing the South China Sea in the east and south. The territory has thriving industries such as textiles, electronics and toys, and a notable tourist industry that boasts a wide range of hotels, resorts, stadiums, restaurants and casinos. This makes it one of the richest cities in the world.

Macau was both the first and the last European colony in China. Portuguese traders first settled in Macau in the 16th century and subsequently administered the region until the handover on December 20, 1999. The Sino-Portuguese Joint Declaration and the Basic Law of Macau stipulate that Macau operates with a high degree of autonomy until at least 2049, fifty years after the transfer. Under the policy of "one country, two systems", the Central People's Government is responsible for the territory's defense and foreign affairs, while Macau maintains its own legal system, police force, monetary system, customs policy, immigration policy, and delegates to international organizations and events.

Macau is situated 60 kilometers (37 mi) southwest of Hong Kong and 145 kilometers (90 mi) from Guangzhou. It consists of the Macau Peninsula itself and the islands of Taipa and Coloane. The peninsula is formed by the Zhujiang (Pearl River) estuary on the east and the Xijiang (West River) on the west. It borders the Zhuhai Special Economic Zone in mainland China. The main border crossing between Macau and China is known as the Portas do Cerco (Barrier Gate) on the Macau side, and the Gongbei checkpoint on the Zhuhai side. Macau Peninsula was originally an island, but a connecting sandbar gradually turned into a narrow isthmus, thus changing Macau into a peninsula. Land reclamation in the 17th century transformed Macau into a peninsula with generally flat terrain, though numerous steep hills still mark the original land mass. Alto de Coloane is the highest point in Macau, with an altitude of 170.6 metres (559.7 ft). With a dense urban environment, Macau has no arable land, pastures, forest, or woodland.

In Macau traffic moves on the left. Macau has a well-established public transport network connecting the Macau Peninsula, Cotai, Taipa Island and Coloane Island. Buses and taxis are the major modes of public transport in Macau. Currently two companies, namely Transmac and Transportas Companhia de Macau, operate franchised public bus services in Macau. The trishaw, a hybrid of the tricycle and the rickshaw, is also available, though it is mainly for sightseeing purposes.

The mixing of the Chinese and Portuguese cultures and religious traditions for more than four centuries has left Macau with an inimitable collection of holidays, festivals and events. The biggest event of the year is the Macau Grand Prix in November, when the main streets in Macau Peninsula are converted to a racetrack bearing similarities with the Monaco Grand Prix. Other annual events include Macau Arts festival in March, the International Fireworks Display Contest in September, the International Music festival in October and/or November, and the Macau International Marathon in December.

Macau preserves many historical properties in the urban area. The Historic Centre of Macau, which includes some twenty-five historic monuments and public squares, was officially listed as a World Heritage Site by UNESCO on July 15, 2005 during the 29th session of the World Heritage Committee, held in Durban, South Africa.
