The Niemodlin dialect (Polish: gwary niemodlińskie, Silesian: niymodlińskie gwar, niymodliński dialekt, pronunciation: 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: [ts], [s], [z], and [dz], respectively). In Niemodlin Silesian phonology a nasalized vowel y ([ɨ̃]) may also occur.
It is closely related to the Prudnik dialect.
