This monographic study presents morphological descriptions of eight species of Padina collected from the Visayas and Mindanao regions of southern Philippines, including distributions of each species and a taxonomic key for all the species examined. Of these species, three are new records for the Philippines, namely: P. fernandeziana Skottsberg and Levring, P. jonesii Tsuda and P. moffittiana Abbott and Huisman. One species, P. antillarum (Kützing) Piccone, represents a new nomenclatural record, which is applied to a Philippine species for the first time. Four species previously reported in the Philippines are reconfirmed and described P. australis Hauck, P. minor Yamada, P. boryana Thivy and P. sanctae-crucis Borgesen. All eight species studied have distromatic thalli, except for P. antillarum which is tetrastromatic. Three of these have indusiate sporangia, namely: P. sanctae-crucis, P. moffittianaand P. fernandeziana.
