Blythswood Square is a square in the Blythswood Hill area of the City of Glasgow, United Kingdom. The square was built as part of a westward expansion of Glasgow city centre. The square was originally intended by the Georgian architects and planners of the time to be the "new" centre of the city, and, although this is largely true from a geographical standpoint, George Square which fronts the Glasgow City Chambers still remains Glasgow's "official" centre.
Today the square is mainly fronted by office buildings retained in the original Georgian façades. In 2009 the former RSAC building was opened as the 5 star Blythswood Square Hotel. The Gardens within the square are private and are owned by all the tenants around the square, the gardens were recently refurbished with new fences erected in a style akin to the fences which were removed previously.
