Gary Gannon (born 18 February 1987) is an Irish Social Democrats politician who has been a Teachta Dála (TD) for the Dublin Central constituency since the 2020 general election.

[5][6] Gannon was involved with Tony Gregory's political group and canvassed for Maureen O'Sullivan at the 2011 general election, before deciding to run against them in 2014 amidst a row over candidate selection.

Gannon again stood as the Social Democrats candidate in the Dublin Central constituency at the 2020 general election and won a seat on the 9th count.

[15][16] In May 2021 Gannon called upon Foreign Affairs Minister Simon Coveney to expel the Israeli Ambassador to Ireland following the outbreak of the 2021 Israel–Palestine crisis.

Minister for Education Norma Foley did not oppose the Bill but called for a nine-month delay on its introduction in order to give time to schools to update their curriculums.

Gannon has called for the Leaving Certificate to be radically reformed, decrying the current system as a “glorified memory test”, which “can be easily manipulated depending on your income”,[22] while supporting a version that incorporates continuous assessment.
