Mieczysław Jan Ireneusz Lubelski (31 December 1886 – 29 April 1965) was a Polish sculptor.
In 1906/07 he entered the Academy of Fine Arts in Warsaw, where he was a pupil of Xawery Dunikowski, and later studied in Berlin. After 1929 he returned to Warsaw. He was very active in the inter-war years and had many exhibitions, including at Warsaw’s Zacheta in 1920. During the German occupation of Poland he joined the Armia Krajowa - Home Army resistance and took part in the Warsaw Uprising, following which he was incarcerated in a Nazi German concentration camp. After the war he settled and worked in England. He created many sculptures for public buildings and churches, perhaps his best known being the Polish War Memorial at Northolt Aerodrome, west London, unveiled in 1948. One of his funerary monuments is a Christ praying in Gethsemani, ceramic in a concrete chapel on the grave of Dr. Antoni Kutek at Brompton Cemetery, London.
His works in Warsaw included: stone knight's armorials and lions decorating the Ministry of Army Affairs (Defence) near Nowowiejska Str., bas-reliefs in the buildings of the National Theatre, the Ministry of Justice and the PKO Bank near Sienkiewicza Str. (all 1924); a bas-relief over the portal of the State Institute of Hygiene and decorative folk sculptures at the Raczyński Palace (both 1925); the Sappers' Monument (1932). Almost all of his works were destroyed during the Second World War. The well-loved Kosciuszko Monument in Liberty Square, central Lodz (1930) which the Germans destroyed in 1939 was re-created by the artist in 1960.
The monument Lubelski designed for the grave of L.L. Zamenhof, the creator of Esperanto, still stands in the Warsaw Jewish Cemetery; and the sculptor appears as a very minor character in the novel A Curable Romantic (2010) by Joseph Skibell.
Lubelski is buried in Brookwood Cemetery, Brookwood, Surrey, England.
