The Descente Korea Munsingwear Matchplay is an annual professional golf tournament hosted in South Korea and sponsored by the clothing company Munsingwear.

The event was not held in 2020 but returned in 2021 with reduced prize money of ₩800,000,000.

Originally 64 players qualified to play 6 rounds of 18-hole match-play over 3 days.

Originally there were matches for all players who reached the last-16 but later only the top 10 played on the final afternoon.

For example, in 2016 Lee Sang-yeop reached the final as the second ranked player, with 3 wins and +8 holes (1up, 6&4, 1up) while Park Sang-hyun with 3 wins and +7 holes (1up, 4&3, 2&1) played in the match to decide 3rd/4th places.
