Leopold Adamovich Mitrofanov (July 2, 1932 – November 26, 1992) was a Russian chess composer, an International Judge of Chess Composition (awarded 1971) and an International Master of Chess Composition (awarded 1980).

He was born in Leningrad (now St. Petersburg) and, by profession, was a chemical engineer.

Beginning in the 1950s, Mitrofanov published over 300 endgame studies, 40 of which were awarded first prizes in competitions. Between 1955 and 1992, he participated in the finals of eight USSR Championships for chess composition. In FIDE competitions, he and Vladimir Korolkov were jointly awarded 3 gold medals. Mitrofanov composed a number of studies jointly with grandmaster Alexander Beliavsky.

In 1967, Mitrofanov's most celebrated chess study was awarded first prize from 250 entries to a tournament commemorating the twelfth-century Georgian poet Shota Rustaveli. Former world champion Mikhail Tal was among the judges. Their report stated that Mitrofanov's entry "doesn't look like any other, and is beyond the rest of the studies."[2] Another judge, composer Alexander Herbstmann, said: "Immediately after the first preview, Mitrofanov's masterpiece created a tremendous impression by the intensity and novelty of the idea. The ranking of the other studies was designated by us beginning with the second place."
