Papua New Guinea competed at the 2016 Summer Olympics in Rio de Janeiro, Brazil, from 5 to 21 August 2016. This was the nation's tenth appearance at the Summer Olympics.

Papua New Guinea Olympic Committee (PNGOC) sent a team of eight athletes, six men and two women, to compete in six sports at the Games, matching the nation's roster size with London 2012.^[2] Attending his fourth and final Olympics as the oldest (aged 34) and most experienced competitor, butterfly swimmer and former top 8 finalist Ryan Pini reprised his role of leading the delegation for the second time as Papua New Guinea's flag bearer in the opening ceremony, the first having done so eight years earlier in Beijing.^[1][3] Apart from Pini, the Papua New Guinean roster also featured 18-year-old taekwondo fighter Maxemillion Kassman, along with his aunt Samantha, and two returning Olympians from London 2012: sprinter Toea Wisil (women's 100 metres) and judoka Raymond Ovinou (men's 66 kg).^[2]

Papua New Guinea, however, has yet to win its first-ever Olympic medal.

From the late 1950s to early 1970s, Papua New Guinea made multiple attempts to join the International Olympic Committee.^[4] After the creation of the Papua New Guinea British Empire and Commonwealth Games Association in 1961, the organization was renamed multiple times before becoming the Papua New Guinea Olympic Committee.^[5][6] After becoming part of the IOC in 1974, Papua New Guinea debuted at the 1976 Summer Olympics and boycotted the 1980 Summer Olympics.^[7][8] Upon their Olympic return at the 1984 Summer Olympics, the country competed in eight consecutive Summer Olympics leading up to the 2016 Summer Olympics.^[4]

Of the eight person team, Ryan Pini appeared in his fourth back to back Olympics and was the country's flag bearer at the opening ceremony.^[9] Returning two-time Olympians from the 2012 Summer Olympics for Papua New Guinea were runner Toea Wisil and judoist Raymond Ovinou.^[10][11] The remaining competitor in athletics, Theo Piniau, appeared in his first Olympics during 2016.^[12] In her Olympic debut, taekwondoist Samantha Kassman was the flag bearer for the nation during the closing ceremony.^[13] Her nephew, Maxemillion Kassman also competed in taekwondo at his first Olympics.^[14][15] The remaining first time Olympic competitors for Papua New Guinea were boxer Thadius Katua and weightlifter Morea Baru.^[16][17]
