The Didymosphaeriaceae are a family of fungi in the order Pleosporales. The family was erected by Anders Munk in 1953.

Taxa have a cosmopolitan distribution, and are saprobic in both woody and herbaceous plants. Some species are parasitic on other fungi. The validity of the family as a distinct taxonomic unit was questioned in a 2014 publication that suggested that the genera Appendispora, Phaeodothis, Roussoella, and Verruculina should be moved into other families.

The type genus is Didymosphaeria, circumscribed by Karl Wilhelm Gottlieb Leopold Fuckel in 1870.
