Comic Fragments Anonymous I is a modern scholarly designation for an anonymous collection of fragments from lost Greek comedies. No biographical details exist for the compiler.

The fragments originate from comedies composed between the 5th and 3rd centuries BCE, spanning the periods of Old, Middle, and New Comedy. The collection comprises excerpts derived from citations in later authors, grammatical works, or papyrus discoveries. While the metadata notes four works, the specific source is not identified in standard repositories. Such fragments typically come from lost plays by dramatists like Aristophanes or Menander, preserved in sources such as Athenaeus or Stobaeus.

These fragments are crucial for reconstructing the history of Greek comedy beyond the few surviving complete plays. They provide evidence for the evolution of comic themes, style, and language, offering insights into lost works and their social and political contexts.
