Boutique Monaco (Korean: 부띠크모나코) is a 117-metre, 27-storey residential skyscraper in the ward of Seocho-gu in Seoul.

The 172-unit residential tower was developed by Bumwoo Co., Ltd. and designed by Minsuk Cho as the working title of "Missing Matrix".

[3] Boutique Monaco was the recipient of the 2008 Silver Emporis Skyscraper Award, beating the much taller 101-story Shanghai World Financial Center.

[5] Boutique Monaco is known for its daring design, which includes several recesses that give the building a unique appearance.

The 15 "missing spaces" were intentionally left empty to comply with the floor area ratio limit of the site.
