Lje (Љ љ; italics: Љ љ) is a letter of the Cyrillic script.
Lje represents a palatal lateral /ʎ/, a sound similar (but not equal) to the palatalized alveolar lateral which is represented by the digraph ЛЬ and pronounced /lʲ/ like the ⟨ll⟩ in "million".
Lje was invented by Vuk Stefanović Karadžić. It is a ligature of Л and Ь.
Lje is used in Serbian and Macedonian, and it corresponds to the Latin digraph ǈ in Serbian and Croatian.
