List of rivers of Ireland
This is an alphabetical list of the main rivers in Ireland as a whole. It includes rivers that flow through the Republic of Ireland and Northern Ireland. Rivers that flow through Northern Ireland are marked with an asterisk (*). The major rivers have their length (in miles and kilometres) given. Also shown are two tables. Table 1 shows the longest rivers in Ireland with their lengths (in miles and kilometres), the counties they flow through, and their catchment areas (in km2). Table 2 shows the largest rivers in Ireland (by mean flow) in cubic meters per second.
Lengths obtained from the Ordnance Survey of Ireland: Rivers and their Catchment Basins 1958 (Table of Reference), and for the rivers Bann and Erne - Notes on River Basins by Robert A. Williams
