L ee Boo-jin is a prominent South Korean businesswoman and a member of the founding family of the Samsung Group, one of the world's largest conglomerates. She is the eldest daughter of the late Samsung chairman Lee Kun-hee. Often referred to by the media as "Little Kun-hee" for her business acumen and resemblance to her father, she has carved out a powerful role for herself within the family empire. She serves as the president and CEO of Hotel Shilla, a luxury hotel and duty-free retail chain that is an affiliate of the Samsung Group.

Lee Boo-jin joined Samsung in 1995 and has been credited with the significant growth and international expansion of the Hotel Shilla brand. Under her leadership, the company has become one of the world's largest duty-free operators, strategically expanding its presence in airports across Asia. Following her father's death in 2020, she and her siblings inherited a multi-billion dollar fortune, which also came with one of the largest inheritance tax bills in history. She is considered one of South Korea's most powerful and wealthiest women, navigating both the complexities of her family's business and a high-profile divorce.
