Verdina Shlonsky (January 22, 1905, Kremenchuk, Ukraine – February 20, 1990, Tel Aviv) was an Israeli composer, pianist, and piano teacher, often described as the leading female Israeli composer of her time.
Shlonsky studied piano in Berlin with Egon Petri and Arthur Schnabel, and composition in Paris with Nadia Boulanger, Edgard Varèse and Max Deutsch. She emigrated to Israel in 1929, where she joined the faculty of the Tel Aviv Academy of Music. Among her noted compositions were "Hebrew Poem" (1931) and "Quartet for Strings", which won an award at the 1949 Béla Bartók Competition in Budapest.
She was the younger sister of poet Avraham Shlonsky.
