Both — Turkey is transcontinental, with ~97% of its land in Asia and a small part in Europe.
Turkey is a transcontinental country that lies in both Asia and Europe. About 97% of its land area — the Anatolian peninsula (Asia Minor) — is in West Asia, while a small portion around Istanbul, called East Thrace, sits in Southeast Europe. Istanbul itself is split by the Bosphorus strait, making it the only major city on two continents.
Geographically and for UN statistics, Turkey is grouped with West Asia. See the Turkey map for detail.
