Topic of this paper is regional identity of Croatian historic region Slavonia. Regional identity in Geography has been studied from the second half of the 20th century, and is divided into identity of a region, and regional consciousness of its inhabitants. After the theoretic introduction with philosophy and sociology references, paper deals with identity of a region through five selected constitutive elements. Regional consciousness is being processed in the second section of the paper, and as part of that second section research survey about external and internal perception of Croatian East has been made. Its results show that natural-geographical characteristics and way of life are the element which is the most important one in the creation of specialty of Slavonia as a region, both in external and internal perception, and at the same time as the element which has the biggest influence on creating regional consciousness of domestic habitants. On the other side, it has been shown that the national identity is the primary level of spatial identity of the majority of the local population. Besides that, research survey touches the topic of popular culture and regional media, where it turned out that popular culture did not significantly affect the perception of the 'outsiders'.
