• Premise of the study: Microsatellite markers were developed for the hemiparasitic plant Melampyrum sylvaticum to investigate the breeding system, genetic diversity, and structure of populations in the United Kingdom, Sweden, and Norway. • Methods and Results: Microsatellites were isolated from genomic DNA using an enrichment protocol. Twenty‐nine loci were characterized in two individuals from each of 15 geographically disparate populations (“global”). Seven polymorphic loci were further characterized in one population (“local”). The number of alleles per locus ranged from two to 12 in the global sample and one to seven in the local sample. The expected heterozygosity ranged from 0–0.75, the observed heterozygosity from 0–0.1, and the inbreeding coefficient from 0.84–1 in the local sample. • Conclusions: The results show the utility of these novel polymorphic microsatellite markers for further conservation genetic analyses. The strong deficit of heterozygosity across all loci in the local sample suggests the species may be inbreeding.
