Karib'il Watar Yahan’m (Sabaean: 𐩫𐩧𐩨𐩱𐩡 𐩥𐩩𐩧 𐩺𐩠𐩬𐩲𐩣, romanized: Krbʾal wtr Yhn’m; fl. late 7th century BCE), sometimes distinguished as Karib'il Watar II, was probably the most important ruler of the early days of the Sabaean Kingdom. He is sometimes regarded as the founder of the kingdom proper, as he was responsible for changing the ruler's title from ("Mukarrib") to "king" (malik).
