Lee Hajin (이하진, 李夏辰, b. 21 June 1988) Korean female professional 4 dan and from 2015-2016 secretary general of the International Go Federation.

In 2005, when she was 17, and a new pro, [ext] Lee Hajin had a sensational streak with victories over Rui NaiWei 9p in the King of Kings round of the Electronic Land Cup tournament. Then she beat Cho HyeYeon (then 6p), the title holder in the Female MyungIn championship. Her fighting skill was remarkable; she has liked studying Life and death problems from a young age.

In 2008, Lee Hajin opened up an [ext] English language blog (dead link) about professional Baduk in Korea.

The blog turned into a book in 2016 "Outside the Board". The German edition "Jenseits des Bretts" is available as hardcover since 2017. For a signing session Hajin showed up on the European Go Congress the same year.

Once worked as a teacher on [ext] http://insei-league.com/. She has visited various go events in Europe and American such as the EGC 2010, EGC 2013, and London Open 2014.

In February 2015, [ext] Lee revealed that she was the recent Youtube Go streamer [ext] Haylee L.

A database of all her Youtube games is maintained by Ger de Groot at [ext] hajin.nl.
