Lee Yeon Woo, known professionally as L:ambda, is a South Korean singer, dancer, and member of ALPHABAT (알파벳).

He made his debut in September 2018 when he joined as ALPHABAT's new vocalist and visual. The group had originally debuted in 2012 as a duo and under another agency, but both members decided to leave YUB Entertainment. One kept the group's concept, and it re-debuted in November 2013 as a 9-member idol group under Simtong Entertainment.

However, they went on hiatus for almost 4 years as the members began enlisting in the military, and the group could not find any stability, switching agencies 3 times before signing with APB Entertainment (APB엔터테인먼트), who decided to add him as a new member just before the launch of their fourth mini-album, "New World".

The group has not officially disbanded, but they have not released any new material since April 2019, and only 3 members remain in the lineup. He entered university in early 2023 and is studying Directing.
