Genome‐wide association studies (GWAS) have associated 76 loci with the risk of developing melanoma. However, understanding the molecular basis of such associations has remained a challenge because most of these loci are in non‐coding regions of the genome. Here, we integrated data on epigenomic markers, three‐dimensional (3D) genome organization, and expression quantitative trait loci (eQTL) from melanoma‐relevant tissues and cell types to gain novel insights into the mechanisms underlying melanoma risk. This integrative approach revealed a total of 151 target genes, both near and far away from the risk loci in linear sequence, with known and novel roles in the etiology of melanoma. Using protein–protein interaction networks, we identified proteins that interact—directly or indirectly—with the products of the target genes. The interacting proteins were enriched for known melanoma driver genes. Further integration of these target genes into tissue‐specific gene regulatory networks revealed patterns of gene regulation that connect melanoma to its comorbidities. Our study provides novel insights into the biological implications of genetic variants associated with melanoma risk.
