Donald P. Wagner (born December 3, 1960) is an American politician, currently serving as a member of the Orange County Board of Supervisors for the 3rd district and chair.

Other previous positions include three active terms as a member of the South Orange County Community College District Board of Trustees.

[8] In April 2021, Wagner inquired about whether COVID-19 vaccines contained "tracking devices" in response to constituents and public commentators making claims falsely asserting so.

In response, Wagner has denied that this was the case and stated that he does not believe in "vaccine conspiracies," while demanding retractions from various media outlets and individuals for publishing what he asserted was "misinformation."

Several media outlets later updated their stories by verifying sources, including a quote from Dr. Chau, who made a clarifying statement that his reaction was at the public commentators and not at Wagner.
