N.D. Zelinsky Institute of Organic Chemistry, Research institute in Gagarinsky District, Russia.

The N.D. Zelinsky Institute of Organic Chemistry of the Russian Academy of Sciences occupies a building at Leninsky Prospekt 47, erected in 1954 to a design by architect Alexei Shchusev. It was founded on 23 February 1934 from the High Pressure Laboratory and the Laboratory of Organic Synthesis. Its departments cover physical and synthetic organic chemistry, natural compounds, catalytic synthesis and computer chemistry.

The facility was established in 1934 through the merger of two separate laboratory operations and gained its current name in the 1950s. During World War II, the institute played an important role supporting war efforts through chemical innovations.

The institute is named after Nikolai Zelinsky, who headed one of its departments from 1936 to 1953, and the name was attached in 1953. Its address, Leninsky Prospekt 47, is a building constructed in 1954 to a design by architect Alexei Shchusev. The institute is a research body of the Russian Academy of Sciences, not a museum, so its culture is that of a working laboratory.

The institute is located in a residential area and is not open to the general public as it is an active research facility. Advance contact with the administration is necessary for any visits or informational requests.

The institute developed a specialized adhesive during the war that enabled field repairs of military equipment under the harshest conditions. This invention was crucial for maintaining war materials on the battlefield.
