The 1859 United Kingdom general election in Ireland produced the last overall victory for the Conservatives in Ireland.

They won a majority of seats on the island despite the Liberals receiving over 60% of the vote; this was partly due to a disproportionately large number of Conservative candidates standing unopposed.

The franchise was restricted to the middle and upper classes.

Electoral reform in subsequent decades saw something of a rise in the Tory vote in Ireland accompanied by a diminution in the number of seats the party won.

This was again due in some degree to the relative numbers of candidates standing unopposed for the two parties.
