L-Ameridelphia huwa superordni ta' mammiferi marsupjali (l-opossumi u l-opossumi bugdiedem). Dan qiegħed ikklassifikat fil-klassi Mammalia, fis-sottoklassi Theria, fl-infraklassi Metatheria, b'żewġ ordnijiet (Paucituberculata u Didelphimorphia). Is-superordni Ameridelphia flimkien mal-Australidelphia jiffurmaw l-infraklassi Metatheria.
L-Ameridelphia jinkludi fih il-marsupjali kollha taż-żewġ kontinenti Amerikani, minbarra il-marsupjal kolokolo jew monito del monte Dromiciops gliroides, li għalkemm huwa mifrux mal-kontinent tal-Amerika t'Isfel jifforma parti mis-superordni Australidelphia.
