Anne M. Gannon (born December 23, 1947) is a Democratic politician who currently serves as the Palm Beach County Tax Collector.

In the Democratic primary, Gannon faced former State Representative Barry Silver, David Niven, Michele Nemo, and Doug Westcott.

Silver sued Gannon "for allegedly defaming his character in campaign literature she distributed" two years prior, while Gannon responded by sending out campaign literature "pointing out Silver's poor driving record" and calling him a "negative person.

Gannon opted to run in the special election, campaigning on increasing efficiency within the office to improve performance,[3] and defeated small business owner Randy Johnson in the Democratic primary with 70% of the vote.

Carney criticized Gannon for "long wait times for service" in the Tax Collector's office and for problems relating to the poor installation of new software to provide property data.
