Achaia is a Polish fantasy series of novels written by Andrzej Ziemiański, published in three volumes in 2002, 2003 and 2004 by the Fabryka Słów. The first two volumes received the Janusz A. Zajdel Award nomination (in 2002 and 2003, respectively); the second one received the Nautilus Award in 2004. All three volumes were reissued in 2011.
Due to an error, the second volume did not include one chapter. It was later published in Science Fiction magazine.
The Achaia series is written as a trilogy and the first three volumes are considered to be the first part of the trilogy. The second part of the trilogy is called Pomnik Cesarzowej Achai.
