The Irish National Federation (INF) was a nationalist political party in Ireland.
The group, which became known as the Anti-Parnellites, had a larger membership than the rump of the INL that stood by Parnell, was led first by Justin McCarthy, then by John Dillon.
The INF was supported by the Catholic clergy, who strongly influenced the general elections of 1892 and 1895, and the by-elections of the period.
The Irish Times reported on 23 February 1893 that "the priests … swarmed at all the polling stations, and kept the voters constantly in view".
As a result, in 1900 the Federation joined the UIL in merging with the INL under the leadership of John Redmond, who had led the Irish National League after Parnell's death, in a newly reformed Irish Parliamentary Party.
