Laanecoorie Weir or Laanecoorie Reservoir, is a water storage for irrigation and domestic purposes on the Loddon River, near the towns of Laanecoorie, Victoria and Eddington, Victoria. It was constructed by contractor Andrew O'Keefe (engineer) in conjunction with Joshua Thomas Noble Anderson. This was the second irrigation scheme for Victoria after the Goulburn Weir. Construction commenced in 1889 and took three years to complete. The largest outlet valves in Victoria, manufactured by the United Iron Work of Abraham Roberts, were installed at the weir in 1891.
