The invention relates to the technical field of biology, in particular to a PCR (Polymerase Chain Reaction) primer group and a kit for jointly detecting various respiratory viruses. The PCR primer group comprises an influenza A virus detection primer pair, an influenza A virus H1N1 detection primer pair, an influenza A virus H3N2 detection primer pair, an influenza B virus detection primer pair, a human respiratory syncytial virus detection primer pair, a human metapneumovirus detection primer pair and a rhinovirus/enterovirus detection primer pair. The kit comprises a multiplex RT-PCR (Reverse Transcription-Polymerase Chain Reaction) reactant, and the multiplex RT-PCR reactant comprises the PCR primer group. The primer group and the kit disclosed by the invention can be used for jointly detecting and identifying seven respiratory viruses, the method is simple to operate, accurate in detection, high in sensitivity and high in specificity, the detection time is remarkably shortened, and a detection result can be obtained within 2-3 hours.
