Jonathan Jay Pollard (born August 7, 1954) is a former intelligence analyst for the US government. In 1984, Pollard sold numerous closely guarded state secrets, including the National Security Agency's ten-volume manual on how the U.S. gathers its signal intelligence, and disclosed the names of thousands of people who had cooperated with U.S. intelligence agencies. He was apprehended in 1985, and in subsequent proceedings agreed to a plea deal, pleaded guilty to spying for and providing top-secret classified information to Israel. Pollard admitted shopping his services—successfully, in some cases—to other countries. In 1987, he was sentenced to life in prison for violations of the Espionage Act.

The Israeli government acknowledged a portion of its role in Pollard's espionage in 1987, and issued a formal apology to the U.S., but did not admit to paying him until 1998. Over the course of his imprisonment, Israeli officials, US-Israeli activist groups and some US politicians continually lobbied for a reduction or commutation of his sentence. In defense of his actions, Pollard said the American intelligence establishment collectively endangered Israel's security by withholding crucial information. Opposing any form of clemency were many active and retired U.S. officials, including Donald Rumsfeld, Dick Cheney, former CIA director George Tenet; several former U.S. Secretaries of Defense; a bi-partisan group of U.S. congressional leaders; and members of the U.S. intelligence community. They maintained that the damage to U.S. national security due to Pollard's espionage was far more severe, wide-ranging, and enduring than publicly acknowledged. Though Pollard argued that he only supplied Israel with information critical to its security, opponents stated that he had no way of knowing what the Israelis had received through legitimate exchanges, and that much of the data he compromised had nothing to do with Israeli security. Pollard revealed aspects of the U.S. intelligence gathering process, its "sources and methods". In 1995, while imprisoned, he was granted Israeli citizenship.

Pollard was released on November 20, 2015, in accordance with federal guidelines in place at the time of his sentencing. On November 20, 2020, his parole expired and all restrictions were removed. On December 30, 2020, Pollard and his second wife moved to Israel and settled in Jerusalem.
