LGツインタワー, Corporate headquarters in Yeongdeungpo District, South Korea.

LG Twin Towers is a pair of 34-storey buildings, 143.87 m tall, at 128 Yeouidae-ro in Yeouido-dong, Seoul. It consists of a west wing, an east wing and a central four-storey glass atrium. The design by Skidmore Owings & Merrill draws on Korean hanok latticework, with window mullions and cheongsachorong lantern motifs in the facade and interiors.

A 54-storey single tower was planned for the Yeouido site in March 1978, with the land bought that June. Height restrictions and unstable conditions abroad led to a 20-storey twin scheme in April 1979, then to the final 34-storey design in April 1981. The US firm Skidmore, Owings & Merrill designed it; construction began in June 1983 and the Lucky-Goldstar Twin Towers opened in 1987, taking the LG name in 1995.

The towers' design draws on Korean traditional architecture: a layered grid structure, borrowed scenery, light and transparency. The four-storey glass atrium's mullion pattern, the facades and interiors echo changhoji-style window lattices, well-frame grids and cheongsachorong lanterns. Since April 2024 the remodelled lower floors, named Connectwin, hold four cafes, a food court and outside-brand restaurants.

The building sits near several metro lines and expressways, making it easily accessible by public transport and car. Visitors should note that this is an active corporate building, so certain areas may be restricted or off-limits.

The towers appear in over a dozen Korean films and dramas, including Bong Joon-ho's 2006 film The Host and the 2013 thriller The Terror Live. The 2019 series Nokdu Flower references the LG headquarters rooftop in dialogue. The complex's glass atrium and grid facade were designed by the American firm SOM, which also handled the 2023–2024 lower-floor renovation.
