OKO (Russian: ОКО, obsolete Russian word for eye, also an abbreviation for Ob'yedinonnyye Kristallom Osnovaniya (Russian: Oбъединённые Кристаллом Oснования, literal meaning Foundations Bound by a Crystal)) is a complex of two skyscrapers located on plot 16 in the Moscow International Business Center (MIBC) in Moscow, Russia. Occupying a total area of about 250,000 square metres (2,700,000 sq ft), the mixed-use complex houses apartments, office space, a 5-star hotel, and other commodities.^[3][4][5][6]

The two skyscrapers, North Tower and South Tower, are among the tallest skyscrapers in Russia, with the latter being the taller of the two. Rising 354.1 m (1,162 ft), the 85-story South Tower, also known as the OKO Apartment Tower or 16a IBC Tower 1, was the tallest building in Russia and Europe when constructed, until it was surpassed by Federation Tower a few months later. The 49-story North Tower, also known as the OKO Office Tower or 16a IBC Tower 2, is 245 m (804 ft) tall and the 11th tallest building in Russia. The complex also has a large car park, rising 12 stories with a height of 44 m (144 ft).^{[3][4][5][6][7][8]}
