Richard Tighe (died 1673) of Woodstock, County Kilkenny, and Rossana, County Wicklow, was a justice of the peace; Mayor of Dublin in 1651; High Sheriff of County Dublin in 1655 and of County Kildare in 1662; and who represented Dublin city in the Second Protectorate Parliament in 1656.
Tighe was born in England and emigrated to Dublin some time before 1649 and probably before 1641. During the Interregnum he supported the English Commonwealth government, probably as a bulwark against the Catholics, rather than a supporter of republicanism, and was against the suppression of the corporation of which the governor Fleetwood was in favour.
The Dublin merchants who most prominently lent support the Commonwealth during the Interregnum were Daniel Hutchinson, Thomas Hooke, John Preston and Richard Tighe. They all served as alderman, were all Mayors of Dublin, all lent money to the regime and all worshipped at Dr Samuel Winter's independent congregation meeting at Church of St. Nicholas Within (Hooke like Hutchinson was an elder of the church).
Tighe was a justice of the peace; Mayor of Dublin in 1651; High Sheriff of County Dublin in 1655 and represented the City of Dublin in the Second Protectorate Parliament in 1656. After the Restoration he was High Sheriff of County Kildare in 1662. During the 1650s Tighe acquired estates in Counties Carlow, Dublin, and Westtmeath.
He died on 20 February 1673 and was buried in the churchyard of St Michan's Church, Dublin.
Tighe married Mary, daughter of Thomas Rooke. She died in 1677 and was also buried in St Michan's Church. Tighe's daughter Anne after she was widowed married a former Mayor of Dublin Alderman John Preston. Tighe's grandson Right Hon. Richard Tighe, M.P., married Barbara, daughter and co-heiress of Christian Borr Esq., of Drinagh and Borrmount, County Wexford.
