Paralaubuca harmandi is a species of freshwater ray-finned fish belonging to the family Xenocyprididae, the East Asian minnows or sharpbellies.

It occurs in the Mekong and Chao Praya in Thailand, Laos, Cambodia and Vietnam.

It is a solitary species which is normally found as scattered individuals in the shallow and medium depths of large rivers.

It moves into floodplains during the monsoon to feed and maybe to breed, and it has also been recorded undertaking short migrations upstream in rivers.

It is fished for by both commercial and subsistence fisheries and it is processed into fermented products in Cambodia while elsewhere it is salted and dried.
