David Buko (1972–2002) was a Papua New Guinean professional rugby league footballer who represented Papua New Guinea in the 1995 and 2000 World Cups.

Buko began his career in the early 1990s and represented Northern Zone before first making the national side in 1993 after helping the Goroka Lahinis win the SP Cup grand final. He played for the national side in both the 1995 and 2000 World Cups.^[2]

In 1999, Buko joined the Western Suburbs Magpies, playing in eight games at both wing and fullback. Buko played in the club's final ever game as a first grade side which was a 60-16 loss against Auckland at Campbelltown Stadium. The club merged with Balmain in 2000 to form the Wests Tigers and Buko was not retained, instead playing in Wagga.^{[citation needed]}
