John Reynolds (1797^[1] – 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,^[2] and Lord Mayor of Dublin in 1850. He was from a prosperous family;^[3] in the 1840s he was secretary of the National Bank of Ireland,^[4] while his brother Thomas Reynolds was Dublin City Marshal.^[5]

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.^[6] 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.^[7] According to Charles Gavan Duffy, it was proved that Reynolds "accepted money extracted from officers for whom he had procured compensation in Parliament".^[8] His grave is in Glasnevin Cemetery.^[9]
