Baek A Yeon is a South Korean singer-songwriter. She graduated from Dongkwang High School and later obtained a bachelor's degree in Vocal from Howon University.

She first appeared on TV in 2011 as a contestant in "K-Pop Star", where she ended up in 3rd place. After the show, she was approached by several companies but decided to sign with JYP Entertainment as Park Jin Young was one of the judges and had already seen her singing.

She made her debut in October 2012 with the mini-album "I'm Baek". She later released the single "Daddy Long Legs" for the SBS drama "Cheongdamdong Alice". The single proved to be more popular than the drama, so other productions contacted her, and she began recording more OSTs.

In May 2015, she released her first self-composed song, "Shouldn't Have" (featuring DAY6's Young K). The song went on to become a sleeper hit, reaching number one on several Korean music real-time charts a month after its release among fierce competition.

In September 2019, her contract with JYP ended, and she decided not to renew it. A few months later, she joined Eden Entertainment (이든엔터테인먼트), a company established by JYP's former vice president of entertainment.

She married her non-celebrity boyfriend in August 2023, and the couple welcomed their first child in September 2024.
