German poet, short-story writer, playwright, and novelist of the early 20th century.

Of Jewish parentage, Schüler settled in Berlin after her marriage to the physician Berthold Lasker in 1894 (divorced 1903). In Berlin she frequented avant-garde literary circles, and her lyric poems and short stories began appearing in periodicals. Her second marriage (1903–11) was to Georg Lewin, the editor of the leading Expressionist journal Der Sturm (Sturm, Der), to whom she gave the pseudonym Herwarth Walden. Her first book, a poetry collection entitled Styx (1902), was followed by Meine Wunder (1911; “My Miracles”), Hebräische Balladen (1913; “Hebrew Ballads”), and several other volumes of lyric poetry. Her other important works are the play Die Wupper (1909), the autobiographical novel Mein Herz (1912; “My Heart”), and the short stories collected in Der Prinz von Theben (1914; “The Prince of Thebes”) and Der Wunderrabbiner von Barcelona (1921; “The Wonder Rabbi of Barcelona”). She emigrated to Switzerland in 1933 after the Nazis came to power in Germany, and in 1940 she resettled in Jerusalem in Palestine. She had always led an eccentric and unpredictable life, and she spent her last years in poverty.

Lasker-Schüler's poems exploit a rich vein of fantasy and symbolism and alternate between pathos and ecstasy in their intensely personal evocation of her childhood and parents, romantic passion, art, and religion. Many of her short stories reinterpret Arabian nights tales in a mode of modern fantasy rich with visual images. Poet Gottfried Benn (Benn, Gottfried) is credited with calling Lasker-Schüler Germany's greatest lyric poet.
