The Philippines is known to host the greatest marine biodiversity per unit area; however, assessment of its sponge biodiversity remains very limited and outdated. We present here the most comprehensive and updated account of Philippine sponge biodiversity, by (1) compiling all known Philippine sponge records from published literature, online databases, museum collections, and grey literature, and (2) checking the taxonomic status of those records against World Porifera Database. Based on our results, a total of 429 sponge species belonging to 175 genera, 90 families, 28 orders, and 4 classes were recorded in the Philippines. Of these, about 190 species have dubious distribution records that need further investigation. Our study also provides updated accounts on the number of species per taxonomic group, a brief analysis of the distribution of the species records, and assessment of available species morphological descriptions,  country, next to Indonesia, with regards to sponges in the Southeast Asian region. However, the current Philippine sponge diversity count is most likely an underestimate given the lack of a national systematic sampling. In addition, there are significant knowledge gaps on the Philippine sponges with regards to morphological character descriptions, specimen images, and molecular information. Therefore, a national systematic sampling must be conducted to confirm the dubious records and improve the knowledge gaps on Philippine sponge biodiversity, distribution, population status, and taxonomic identification.
