P Cygni (34 Cyg) adalah bintang variabel yang terletak di konstelasi Cygnus. Sebutan "P" pada awalnya dinyatakan oleh Johann Bayer di Uranometria untuk nova. Berjarak sekitar 5.000 hingga 6.000 tahun cahaya (1.500–1.800 parsec) dari Bumi, P Cygni adalah bintang hiper raksasa variabel biru bercahaya (VBR) tipe spektral B1Ia+ yang merupakan salah satu bintang paling bercahaya di Bima Sakti.
