The disbarment order of the U.S. Court of Appeals for the District of Columbia had been expected.
"When a member of the bar is convicted of an offense involving moral turpitude, disbarment is mandatory," the appeals court ruled.
Last May, a court panel that oversees lawyer ethics recommended that Libby be stripped of his law license in Washington. The Board on Professional Responsibility then found that Libby's conviction for lying to the FBI about the case of former CIA operative Valerie Plame amounted to "crimes that involve moral turpitude."
"This action is required by the rules following a conviction regardless of the merits of the case, and for that reason Mr. Libby expected and did not oppose the court's order," said Libby attorney William Jeffress.
Libby, the former chief of staff to Vice President Dick Cheney, was first licensed to work as a lawyer in Washington in 1978. His membership with the D.C. bar also was suspended for failing to pay his dues, records show.
