免疫遗传学（英语：Immunogenetics 或 Immungenetics）是一个生物学分支，研究免疫系统和遗传之间的关系。

Immunogenetics or immungenetics is the branch of medical research that explores the relationship between the immune system and genetics.

Autoimmune diseases, such as type 1 diabetes, are complex genetic traits which result from defects in the immune system. Identification of genes defining the immune defects may identify new target genes for therapeutic approaches. Alternatively, genetic variations can also help to define the immunological pathway leading to disease.
