Jill Hazelbaker is a political campaign spokesperson and campaign staff member for candidates of the Republican Party in the United States, currently working as as a "media strategist and spokesperson" on New York City Mayor Michael Bloomberg's re-election campaign.

Hazelbaker was the national communications director for John McCain's presidential campaign. A MSNBC online piece listed her as one of eight in McCain's "candidate brain trust," their shortlist of the candidate's closest advisers.

Hazelbaker's name earlier came to public attention in connection with an accusation of astroturfing at the time she was the press secretary for Tom Kean Jr.'s 2006 campaign for the US Senate in New Jersey. Hazelbaker denied involvement in those activities.
