Hedysarum orumiehense Ranjbar and H. neyshaboricum Ranjbar, two new species endemic to Iran, are described and illustrated. Both new species belong to section Multicaulia Boiss. in Hedysarum L. (Fabaceae) and are distinct among Iranian species. The former species is closely related to H. atropatanum Bunge ex Boiss. and is distinguished by its glabrous pods, the leaflets in eight to 11 pairs, and the longer corolla wings (10–11 mm). The latter is distinguished from H. paucifoliolatum Ranjbar & Olanj by its longer peduncles (20–27 cm), stipules (7–9 × 4–5 mm), and corolla standard (15–17 × 13–14 mm). Both H. orumiehense and H. neyshaboricum are evaluated as Vulnerable (VU) according to IUCN Red List criteria.
