Chaim Yehuda ("Yudel") Krinsky (born December 3, 1933, in Boston, Massachusetts) is an ordained rabbi and a member of the Chabad-Lubavitch movement.
He has served in various positions of the movement's administrative staff since 1954, and as a personal secretary to its chief rabbi (along with Yehuda Leib Groner and Binyomin Klein).
In 1988, after the passing of his wife, Chaya Mushka Schneerson, Schneerson named Krinsky an executor of his will.
Today, Krinsky is among the most influential figures within the Chabad movement.
