Petar Parchevich or Petar Mihaylov Parchev (c. 1612–23 July 1674) is a Bulgarian Roman Catholic archbishop, diplomat, scholar, baron of Austria and one of the architects behind the anti-Ottoman Chiprovtsi Uprising.

A native of Chiprovtsi and one of Bulgaria's most educated people of the 17th century, Parchevich is among the leaders of the Bulgarian Catholics.

His numerous diplomatic visits to the royal courts of Europe are mostly in an attempt to garner support for an anti-Ottoman uprising in Bulgaria, which he does not live to witness.

Nevertheless, his efforts in defending Christianity earn him a noble title from the Austrian emperors, and he takes up several important positions within the Roman Catholic ecclesiastical hierarchy.
