The Niemodlin dialect (Polish: gwary niemodlińskie, Silesian: niymodlińskie gwar, niymodliński dialekt, pronunciation: pronounced as /ɲɨmɔˈdliɲski ˈdjalɨkt/) is a Silesian dialect, used in the parts of the city of Niemodlin, Poland. It slightly differs from standard Silesian by having a characteristic pronunciation called mazuration (mazurzenie), which means that the consonants cz sz ż dż are pronounced as the alveolars c s z dz (IPA: pronounced as /[ts]/, pronounced as /[s]/, pronounced as /[z]/, and pronounced as /[dz]/, respectively). In Niemodlin Silesian phonology a nasalized vowel y (pronounced as /[ɨ̃]/) may also occur.
It is closely related to the Prudnik dialect.
