An adjustable arc sprinkler nozzle comprises a nozzle body which has a plurality of radial channels for forming radial streams out of water flowing into the nozzle from a sprinkler body to which the nozzle is joined. A crown shaped deflector member includes a plurality of vertically extending fingers which operatively coact with the radial nozzle channels to restrict the amount of water flowing therethrough. A selectively operable adjusting member is cooperatively engaged with the deflecting member for moving the deflecting member vertically relative to the nozzle body to vary the position of the fingers relative to the channels to change the amount of water restriction imposed by the fingers on the water flowing through the channels, whereby the throw radius is selectively adjusted by vertical movement of the deflecting member. A selectively operable locking member, i.e. a locking cover or a two-position locking pin, is provided for preventing movement of the adjusting member to lock out any adjustment in the throw radius.
