Yordan Piperkov (1870–1903) (Bulgarian: ?????? ??????? ????????); (Macedonian: ?????? ????????), widely known as Yordan Piperkata, (Bulgarian: ?????? ?????????, Macedonian: ?????? ?????????) was a Bulgarian revolutionary from the early 20th century, member of the Internal Macedonian-Adrianople Revolutionary Organization (IMARO).
According to the post-WWII Macedonian historiography, he was an ethnic Macedonian.
Because in many documents of 19th century the Macedonian Slavs were referred to as "Bulgarian", Macedonian scientists argue that they were "Macedonian", regardless of what is written in the records.
