Nikolay Aleksandrovich Alekseyev (Russian: Николай Александрович Алексеев, 1852 –25 (OS 13) March 1893) was the elected mayor of Moscow in 1885–1893. Alekseyev is credited with construction of the city's first sanitation system, the first pressurized water supply network reaching individual houses, a psychiatric hospital and 30 new public schools. Alekseyev reorganized the city finances, significantly increasing the share of non-tax revenue from city-owned commercial ventures, and was known for unorthodox and successful fundraising campaigns for the municipal charities. Alekseyev was a long-time sponsor of Moscow Conservatory and local musicians; during his tenure the city acquired the Tretyakov Gallery.
