Mr. de Blasio served in Mr. Clinton's administration as a regional director of the Department of Housing and Urban Development and was the campaign manager for Hillary Rodham Clinton's successful run for the Senate in 2000. Mrs. Clinton will also attend the inauguration.

"I was honored to serve in President Clinton's administration and on Secretary Clinton's campaign for U. S. Senate, and I am honored again that they will both join our celebration for all of New York City," Mr. de Blasio said in the statement. "Wednesday's ceremony will be an event for every New Yorker from all five boroughs, and Chirlane and I couldn't be more excited to have President Clinton and Secretary Clinton stand with us," he said, referring to his wife, Chirlane McCray.

The ceremony, which will begin at noon, will be held on the steps of City Hall in Lower Manhattan. Last week, Mr. de Blasio set aside 1,000 tickets to the inauguration for the general public.

He will be sworn in on a Bible once owned by President Franklin D. Roosevelt that will be on loan from his presidential library in Hyde Park, N.Y., the transition team said.

Mr. de Blasio's transition team said that Lissette Ortiz, a senior at Medgar Evers College, will introduce Mr. Clinton. A Bronx resident, Ms. Ortiz was born in the Dominican Republic and moved to the United States when she was 15. She plans to pursue a career in public administration.
