===Prefecture===
As a part of the 2011 Kallikratis government reform, the former Euboea Prefecture ({{langx|el|Νομός Εύβοιας}}) was transformed into a regional unit within the Central Greece region, without any change in boundaries. At the same time, the municipalities were reorganised, according to the table below.<ref name=Kallikratis/> {| class="wikitable" ! New municipality !! Old municipalities !!
