Yes, Koreans in North Korea and South Korea both speak Korean. However, since the countries have been separated for some time and haven't had much contact, you can expect that some new dialectical differences are developing. However, my guess is that probably some different dialects of Korean were present in different regions even before the country got split up.
Does north Korean speak the same language with south Korean ?
