There are a number of commonly occurring weeds or invasive plant species in Queensland, Australia. These plants typically produce large numbers of seeds, often excellent at surviving and reproducing in disturbed environments and are commonly the first species to colonise and dominate in these conditions. Weeds may reduce native biodiversity, affect agricultural productivity, the environment, human health and amenity.

Some of the more common weeds of Queensland are listed below. Weeds that are not yet common or established but pose a significant threat are identified by an asterisk. Weeds that are identified as Weeds of National Significance are noted as "WoNS".
