GS Square Department Store(GS스퀘어백화점) was a South Korean department store franchise, owned by GS Group. It had 3 branches in Seoul Metropolitan Area. The original name of the department stores used to be LG Department Store owned by LG Group, but as GS group was separated from LG group in 2005, the company altered the name into "GS Square."
As Lotte Shopping took over the three GS Squares along with GS Marts, these stores were renamed as Lotte Department Store starting May, 2010.
