Boa Kwon (Korean: 권보아, Kwon Boa, born November 5, 1986), commonly stylized and known by her stage name BoA, which is a backronym  for Beat of Angel,  is a Korean singer, active in South Korea, Japan, and the United States. Born and raised in Gyeonggi-do, South Korea, BoA was discovered by SM Entertainment talent agents when she accompanied her older brother to a talent search. In 2000, after two years of training, she released ID; Peace B, her debut Korean album, under SM Entertainment. Two years later, she released her debut Japanese album, Listen to My Heart, under the Avex label. On October 14, 2008, under SM Entertainment USA, a subdivision of SM Entertainment, BoA debuted in the United States with the single "Eat You Up" and released her debut English-language album, BoA  on March 17, 2009.

Influenced by hip hop and R&B singers as Nelly and Janet Jackson, many of BoA's songs fall into those genres. As the singer feels she does not "have any talent for writing [songs]", the writing and composition of her songs are handled mostly by her staff; for this reason, she has drawn some criticism. (Though only a few of her songs are self-written, BoA began composing on her own with her Japanese debut album Listen to My Heart, in which she co-wrote and composed the song "Nothing's Gonna Change".)

BoA's multilingual skills (she speaks Japanese and conversational English along with her native Korean and has recorded songs in Mandarin Chinese) have contributed to her commercial success in South Korea and Japan and her popularity throughout East Asia. She is the only non-Japanese Asian to have two million-selling albums in Japan and is one of only two artists to have six consecutive number-one studio albums on the Oricon charts since her debut.
