Joseph Nolan (1846 – 14 September 1928) was an Irish nationalist politician and Member of Parliament (MP) in the House of Commons of the United Kingdom of Great Britain and Ireland. As a member of the Irish Parliamentary Party, he represented North Louth from 1885–92, and South Louth from 1900-18. The Irish Times (15 September 1928) said he was "One of the Fenians whom Parnellism conquered."
Nolan was born at Castleblayney, County Monaghan. He married Mary Flinn, who had been born in County Down, in 1884. She was 12–14 years his junior. Together they had nine children, of whom two died young, leaving by 1911 three sons and four daughters. Nolan was originally a schoolteacher, in Ireland and then at a reformatory school in Liverpool. He later became manager of the Aquarium and Casino in New Brighton on the Wirral Peninsula near Liverpool, and this was his job at the time of his first election to Parliament for the new seat of North Louth in the Nationalist landslide of 1885. In this election, as the official Irish National League candidate supported by Charles Stewart Parnell, he defeated Philip Callan, who had previously sat for Co. Louth as a Home Ruler but had fallen out with Parnell and now stood as an Independent Nationalist. Nolan was then returned unopposed in 1886.
When the Irish Parliamentary Party split over the leadership of Charles Stewart Parnell in 1890, Nolan supported Parnell. At the following election in 1892 he stood in South Louth but was defeated by an Anti-Parnellite by more than 2 to 1. At the general election of July 1895 he stood in the North Louth seat again, challenging the prominent Anti-Parnellite incumbent Timothy Michael Healy, but was again defeated, this time by 3 to 2. In a by-election the following September, he came within 88 votes of winning Limerick City as a Parnellite.
