The Jadro is a watercourse in Dalmatia, Croatia, that discharges into the Adriatic Sea. The upper reaches of the Jadro River, as well as its source, Jadro Spring, are protected as an ichthyological nature reserve, partly due to the presence of an endemic species of soft-mouthed trout.

Contemporary studies indicate favourable water quality levels of the river near the headwaters at Jadro Spring.
