Lee Jae-yoon (Korean: 이재윤; Hanja: 李在允, born December 15, 1984) is a South Korean-Canadian[8] actor and model.

[9][10][7] He is best known for his roles in the television dramas My Love By My Side (2011), Heartless City (2013), Weightlifting Fairy Kim Bok-joo (2015–2016) and Mother (2018).

Besides the very competitive auditions for roles, there were also the suggestions and offers for him to do cosmetic surgery; to trim his nose, soften his jawline, and straighten his teeth.

[1] But Lee said he decided not to do any of the procedures because he felt he was doing away with what his parents have naturally given him in terms of appearance, and that he hated the thought of getting any aesthetic enhancements.

[4] Lee has revealed in an interview that he would be pleased to find a romantic partner in the future who is also into sports and the active lifestyle, one with whom he can swim, run, or dive.

[4][8] As an athlete, Lee has been working closely with the sportswear and sports gear brand Puma, both as an endorser and ambassador.
