Haplogroup S-M230, also known as S1a1b (and previously as S* or K2b1a4), is a Y-chromosome DNA haplogroup. It is by far the most numerically significant subclade of Haplogroup S1a (and its sole primary subclade, Haplogroup S-P405).
S-M230 is commonly found among populations of the highlands of Papua New Guinea (Kayser 2003). It is also found at lower frequencies in adjacent parts of Indonesia and Melanesia. (Kayser 2003 Cox 2006)
