József Borovnyák or Borovnják (Slovene: Jožef Borovnjak; 1826 – 19 September 1909) was a Prekmurje Slovene writer, politician, and Roman Catholic priest in Hungary.

Borovnják was born in the village of Ivanócz (later Alsószentbenedek, Slovenian Ivanovci).

Borovnják first served as a priest from 1851 to 1852 at the Istvánfalvian Church in the village of Apátistvánfalva (Vas Country).

Borovnják was a defender of the local Prekmurje Slovene language.

In 1877 he posthumously reprinted Miklós Küzmics' Prekmurje Slovene translation of the gospels.
