Charlie Wi (born 3 January 1972) is a South Korean professional golfer who plays on the PGA Tour. He has also previously played on both the European and Asian Tours.

Wi was born in Seoul, and moved to Los Angeles, California, United States at the age of 10. He attended the University of California, Berkeley, after briefly attending the University of Nevada, Reno and had a successful amateur career before turning professional in 1995.

Early in his career, Wi played all over the world, competing on the European, Asian and Japanese tours. He had most success on the Asian Tour where he finished second on the money list in 2001, just behind Thongchai Jaidee, having won three times during the season.

Wi earned his place on the PGA Tour for 2005 when he successfully negotiated all three stages of the 2004 qualifying school. However, he did not do well enough in his rookie season to retain his card, and went back to play on the Asian Tour in 2006, finishing 4th on the money list. He also competed on the second tier Nationwide Tour, before returning to qualifying school where he regained his place on the PGA Tour for 2007.

Kevin Sangwook Na (born September 15, 1983) is a Korean American professional golfer currently playing on the PGA Tour.

Na was born in Seoul, South Korea. His family emigrated to the United States when he was eight years old. He turned professional at age 17 in 2001. He later naturalized as an American citizen. Na lives in Las Vegas, Nevada.

Na has played on the Asian Tour (with a win at the 2002 Volvo Masters of Asia), European Tour, Nationwide Tour (with a win at the 2006 Mark Christopher Charity Classic), and PGA Tour (with a win at the 2011 Justin Timberlake Shriners Hospitals for Children Open). In 2009 he had nine top-10 finishes and finished in 19th place on the money list, securing his entry to The Masters and the U.S. Open for the first time.

In February 2011, Na was in contention to win his first PGA Tour title at the Northern Trust Open. He entered the final round in a tie for 2nd at -9, one stroke behind the Australian Aaron Baddeley. However a run of four bogeys in the first ten holes ended Na's chances of victory. He would eventually fight back on the back nine and a vital birdie on the par-five 17th sealed a top-three finish, behind eventual winner Baddeley and the Fijian Vijay Singh.
