The 2015 AFC Asian Cup final was a football match which took place on 31 January 2015 at the Stadium Australia in Sydney, Australia, to determine the winner of 2015 AFC Asian Cup. It was played between South Korea and hosts Australia. Australia won the match 2–1 in extra time and qualified for the 2017 FIFA Confederations Cup in Russia.

Before the match, South Korea had reached the AFC Asian Cup final three times (1972, 1980 and 1988), finishing runners-up in all attempts since a knockout system was introduced. However, prior to such a system, South Korea had won the tournament twice (1956 and 1960). Australia had reached one final (2011) since moving to the Asian Football Confederation from the Oceania Football Confederation in 2006.

Prior to the tournament, the two finalists had previously met each other 26 times, with South Korea winning nine games and Australia ten. The two sides first met on 14 November 1967 in the final of the 1967 Quoc Khanh Cup in South Vietnam. Australia won the match 3–2 and secured the nation's first honour in international football. The last meeting between the two teams, a 0–0 draw, took place on 20 July 2013, at the 2013 EAFF East Asian Cup in South Korea. Australia, who began the 2015 Asian Cup as one of the favourites, was ranked 100 in the FIFA World Rankings and tenth among AFC teams, while South Korea was ranked 69 overall, and third among AFC teams.

South Korea entered the 2015 Asian Cup as two-time Asian champions, having won the first two instalments of the tournament. However, the 2015 final was South Korea's first appearance in the final in 26 years and only their third appearance in the final since a knockout system was introduced. South Korea was first crowned champions of Asia in the inaugural 1956 edition of the Asian Cup, held in Hong Kong. There, the competition was formatted as a round-robin tournament between four teams with no final, and South Korea won the tournament after just three matches. South Korea successfully defended their title in 1960 on home soil. It was not until 1972 that South Korea would get the chance to contest the Asian title again, in the tournament's first ever final after the change to a knockout format. South Korea lost the match against Iran 2–1 in extra time. South Korea again failed to win the final match in 1980, when they lost 3–0 against host nation Kuwait. In 1988, South Korea contested the final against Saudi Arabia in Qatar. After remaining scoreless at the end of extra time, the match was decided in a penalty shoot-out, with the Saudis taking home the title through a 4–3 win.

The 2015 final was Australia's second consecutive time contesting an Asian Cup final out of only three appearances since moving to the Asian Football Confederation from the Oceania Football Confederation in 2006. In 2011, Australia lost to Japan 1–0 in extra time.

Stadium Australia was announced as the venue of the 2015 final on 27 March 2013, along with the announcement of the five stadiums used in the tournament. The venue was chosen in preference to Melbourne Rectangular Stadium, which was instead selected to host the opening match of the tournament between Australia and Kuwait. The stadium chosen for the final had the largest capacity of those used in the tournament, with a capacity crowd of 84,000. It was first opened in 1999, and was built to host the 2000 Sydney Olympics. The venue has played host to a number of Sydney's major sporting events, and it was used for seven matches in the 2015 AFC Asian Cup, including four group matches, a quarter-final and semi-final match, as well as the final.

Both South Korea and Australia were drawn into Group A of the 2015 AFC Asian Cup, along with lower ranked sides Oman and Kuwait. After winning all three group matches, South Korea finished first in the group. Host nation Australia finished second in the group to progress to the knockout stage of the tournament.

South Korea's first match against Oman was played at Canberra Stadium. A single goal by Cho Young-cheol in the 46th minute during injury time was enough for the South Korean's to take all three points. South Korea played their second match against Kuwait in Canberra. A goal by Nam Tae-hee saw the game end 1–0. In their final group match South Korea played Australia at a sold out Brisbane Stadium. The match would decide the final standings of the group, with South Korea needing a win to finish top in the group. A goal from striker Lee Jung-hyup in the 33rd minute gave South Korea their third 0–1 win in the tournament. South Korea progressed to the quarter-final stage to face Group B runner-up Uzbekistan. After a goalless 90 minutes, the match was taken into extra time, where Son Heung-min found the net twice to end the game 2–0. In the semi-finals, South Korea took on Iraq in Stadium Australia. Goals by Lee Jung-hyup and Kim Young-gwon ended the match 2–0, with South Korea progressing to the 2015 final.
