Port Moresby (; Tok Pisin: Pot Mosbi), also referred to as Pom City or simply Moresby, is the capital and largest city of Papua New Guinea. It is one of the largest cities in the southwestern Pacific (along with Jayapura) outside of Australia and New Zealand. It is located on the shores of the Gulf of Papua, on the south-western coast of the Papuan Peninsula of the island of New Guinea. The city emerged as a trade centre in the second half of the 19th century. During World War II, it was a prime objective for conquest by the Imperial Japanese forces during 1942–43 as a staging point and air base to cut off Australia from Southeast Asia and the Americas. As of the 2011 census, Port Moresby had 364,145 inhabitants. An unofficial 2020 estimate gives the population as 383,000. The place where the city was founded has been inhabited by the Motu-Koitabu people for centuries. The first Briton to see it was Royal Navy Captain John Moresby in 1873. It was named in honour of his father, Admiral of the Fleet Sir Fairfax Moresby. Although Port Moresby is surrounded by Central Province, of which it is also the capital, it is not part of that province but forms the National Capital District. The traditional landowners, the Motu and Koitabu people, are represented by the Motu Koita Assembly. Port Moresby hosted the APEC summit in November 2018. However, there were concerns about security given the capital's reputation for violent crime.

The Hubert Murray Stadium is a sports venue located in Port Moresby, the capital city of Papua New Guinea. It was developed for the 1969 South Pacific Games on reclaimed land at Konedobu that had previously been shoreline mangroves. The athletics events and the opening and closing ceremonies were held at the new stadium, which was named after Sir Hubert Murray, a former lieutenant governor. With an initial capacity of approximately 15,000 spectators, it was used for soccer and school athletic events after the 1969 games. In late 2003, a three-stage redevelopment of the site at a cost of K120 million via a public-private partnership began to expand the capacity to seat 25,000 people. The redeveloped stadium will be used for rugby league, rugby union, and soccer in a venue fit for FIFA standards, naturally grassed and with lighting suitable for television broadcasting of night events.The plans for the six-storey main stand include eight restaurants and a gymnasium with the facilities to host the weightlifting competition for the 2015 Pacific Games. Australian football and cricket are to be catered for by further expansion in stage three of the redevelopment.

The Battle of Port Moresby was an aerial battle fought between the Royal Australian Air Force (RAAF) and United States Army Air Force (USAAF) on one side and the Imperial Japanese Army and Imperial Japanese Navy on the other between 3 February 1942 and 17 August 1943 over Port Moresby, Papua. At the start, the defenders consisted only of Australian Army anti-aircraft batteries and machine-guns, but by late March had been strengthened by the arrival of Kittyhawk fighters from No. 75 Squadron RAAF. However, in just nine days they lost 11 aircraft and only the arrival of replacements enabled the unit to maintain ten serviceable machines. According to the Australian government: On 31 March, the Australians were joined by the American 8th Bombardment Squadron with A-24 bombers and for two weeks in May by six P-39 Airacobras of the American 36th Pursuit Squadron. Despite the American assistance, the daily air battles over and around Port Moresby by 1 May had reduced No. 75 Squadron RAAF to just three airworthy machines. The American 35th, and the full 36th, Pursuit Squadrons arrived to relieve the Australian squadron. During their time in Port Moresby 75 Squadron had lost 21 aircraft and 12 pilots. The Battle of the Coral Sea, which was fought mostly in the waters south-east of Papua in early May, diverted a Japanese naval attack against Port Moresby and removed the immediate threat. However, by May 1942 the Japanese had established themselves in the arc of islands north and east of the island of New Guinea as well as in the region around Lae and Madang on the north coast of the mainland.
