Ahnenblatt is a genealogy software application for Microsoft Windows developed by German programmer Dirk Böttcher. It features data entry, plausibility check and creation of charts and reports. The software imports and exports GEDCOM files and exports Web pages.

The name of the software is German and literally means "ancestor sheet".
