John Reynolds (Dublin politician)

John Reynolds (1797 – 21 August 1868) was an Irish Repeal Association politician who was a Westminster M.P. for Dublin City from the 1847 election to the 1852 election, and Lord Mayor of Dublin in 1850. He was from a prosperous family; in the 1840s he was secretary of the National Bank of Ireland, while his brother Thomas Reynolds was Dublin City Marshal.

Reynolds regarded the Repeal Association as a vehicle for advancing the local interest of Dublin rather than the constitutional question of repeal of the Acts of Union 1800. The Dublin merchant and trade lobby lost influence in the Association to professional men in the mid-1840s, but regained it after Daniel O'Connell's death in May 1847, with Reynolds, then an alderman, coming to prominence. According to Charles Gavan Duffy, it was proved that Reynolds "accepted money extracted from officers for whom he had procured compensation in Parliament". His grave is in Glasnevin Cemetery.
