Yitzhak Lamdan (Hebrew: יצחק למדן) (born 7 November 1899; died 17 November 1954) was an Israeli poet, translator, editor and Hebrew columnist.
Yitzhak Lamdan was born in the Ukraine (then part of the Russian Empire) in 1899. He immigrated to Palestine in 1920, during the Third Aliyah.
In the 1920s, he wrote a poem called "Masada" about the Jewish struggle in a world full of enemies. Lamdan's poem is said to have inspired the uprising in the Warsaw Ghetto.
From 1954 until 1983, the Ramat Gan Municipality, in conjunction with the Hebrew Writers Association in Israel, awarded the annual Lamdan Prize in his memory, for literary works for children and youth.
