The northern river shark or New Guinea river shark (Glyphis garricki) is a species of requiem shark, in the family Carcharhinidae, found in scattered tidal rivers and associated coastal waters in northern Australia and in Papua New Guinea. This species inhabits areas with poor visibility, soft bottoms, and large tides, with immature sharks ranging into fresh and brackish water. It is similar to other river sharks in having a stocky grey body with a high back, tiny eyes, and broad fins. It measures up to 2.5 m (8.2 ft) long.
Northern river sharks are likely piscivorous. This species is viviparous, with females bearing litters of 9 young possibly every other year before the wet season. Very rare and facing threats from commercial and recreational fishing, and perhaps also habitat degradation, this species has been assessed as Vulnerable by the International Union for Conservation of Nature.
