Ernst Laske (born 9 August 1915 in Berlin; died 11 May 2004 in Kibbutz Bror Chail, Israel) was a German-Israeli book antiquarian and bibliophile.
In reaction to the rise of the Nazis, he joined the Zionist movement, but hesitated for a long time to leave Germany.
For about two decades, he ran the antiquarian bookshop in the "Landsberger" bookstore on Tel Aviv's Ben Jehuda Street.
He gladly invited his customers - among them publishers and antiquarians from Germany - to his apartment on Jabotinsky Street in Tel Aviv.
He spent the last years of his life in a retirement home on Kibbutz Bror Chail in southern Israel, near his grandson's family.
