Griffith's Valuation was the general valuation of all rateable property in Ireland and was completed between the years 1847 and 1864. It was named after Richard Griffith, Commissioner of Valuation. The valuations were published in a series of over 300 volumes, detailing the names of all the property occupiers in Ireland and the value of their house and land.

The complete name is "Griffith's Primary Valuation of Rateable Property in Ireland".

The purpose was to establish the level of rates payable by each landholder or leaseholder. It lists the majority of land- or house-holders in the country giving the townland and description of the property (e.g. land; house; land and house; or house, out offices/out buildings, and land). It also lists the landlord and the annual valuation, however it does not list the age of the landholder or names of family members.

The years that the Valuation was completed for each Irish County are listed below.
