The Moscow International Business Center (MIBC), also known as Moscow-City, is an under-construction commercial development in Moscow, the capital of Russia. The project occupies an area of 60 hectares, and is located just east of the Third Ring Road at the western edge of the Presnensky District in the Central Administrative Okrug. Construction of the MIBC takes place on the Presnenskaya Embankment of the Moskva (river), approximately 4 kilometers (2.5 mi) west of Red Square.

The complex is home to the highest numbers of skyscrapers in Europe. The Government of Moscow first conceived the project in 1992, as a mixed development of office, residential, retail and entertainment facilities. An estimated 250,000 – 300,000 people will be working in, living in, or visiting the complex at any given time. By 2016, twelve of the twenty-three planned facilities of the MIBC were already built; seven buildings were under construction; and four were in the design stage.

Before construction began, the area was a stone quarry and industrial zone, where most of the buildings were old factories that had been closed or abandoned. A public company, CITY, was created in 1992, to oversee the initial creation and development of Moscow City as well as its subsequent usage. CITY is also a general contractor and both landlord and lessor. Overall responsibility for the architectural planning and design of Moscow City belongs to the architectural studio No. 6, which is a part of the large Moscow practice Mosproject-2 named after Mikhail Vasilyevich Posokhin. This group, headed by Gennady Lvovich Sirota, who is officially the Chief Architect of Moskva-Citi, is in charge of overseeing the design of the complex as a whole and agreeing the details of individual projects. Each building lot has its own investor and architect. By 2014, the volume of investments in Moskva-City was approximately $12 billion.

Established in the spring of 1992, the PJSC City Company manages the creation and development of the MIBC. On 30 December 1994, the Government of Moscow authorized PJSC City to act as the managing company for the MIBC and to negotiate with third parties to help develop the MIBC. As of February 2014, the company was owned by the Solvers Group, led by Oleg Malis.

Roof height, max height, and floors apply to the tallest building of the respective complex. Completion of construction applies to the building in each complex completed last.

The Bagration Bridge is a pedestrian bridge that goes over the Moskva (river). It connects Tower 2000 and the rest of the MIBC complex.

Major thoroughfares that connect to the MIBC are the Third Ring Road, 3rd Magistralnaya street, and the Presnenskaya Embankment.

To correspond with the growing MIBC, new highways and interchanges were built to connect the MIBC with the main transport arteries of the city. These projects include the ten-lane Dorogomilovsky Bridge of the Third Ring Road over the Moskva (river), the Third Ring Road interchange with Kutuzovsky Avenue, and the extension of the Presnenskaya Embankment. Existing roads were reconstructed and rearranged.
