ハプログループN (Y染色体)(ハプログループN (Yせんしょくたい)、英: Haplogroup N (Y-DNA))とは分子人類学において人類の父系を示すY染色体ハプログループ(型集団)の分類で、「M231」以下の系統に位置すると定義されるものである〔The b2/b3 deletion in the AZFc region of the human Y-chromosome is a characteristic of Haplogroup N-M231 haplotypes. This deletion, however, appears to have occurred independently on four different occasions. Therefore this deletion should not be thought as a unique event polymorphism contributing to the definition of this branch of the Y-chromosome tree (ISOGG 2012).〕。 ==起源・分布== Y染色体のハプログループNは、25000年前~20000年前〔Shi H, Qi X, Zhong H, Peng Y, Zhang X, et al.
