ISO 8859-3, also known as Latin-3 or "South European" is an 8-bit character encoding, part of the ISO 8859 standard. It was designed originally to cover Turkish, Maltese and Esperanto, though the introduction of ISO 8859-9 superseded it for Turkish.

The encoding remains popular with users of Esperanto, though use is waning as application support for Unicode becomes more common.

As with all varieties of ISO 8859, the lower 7 bits are equivalent to ASCII.
