The notion of (closed) \L{}ukasiewicz fuzzy ideal is introduced, and several properties are investigated. The relationship between \L{}ukasiewicz fuzzy subalgebra and \L{}ukasiewicz fuzzy ideal is discussed, and characterization of a \L{}ukasiewicz fuzzy ideal is considered. Conditions for a \L{}ukasiewicz fuzzy subalgebra to be a \L{}ukasiewicz fuzzy ideal are provided, and conditions for the $\in$-set, $q$-set and $O$-set to be ideals are explored.
