The majority of Hudson residents who practice a religion are likely Roman Catholics or Protestants, based on the churches existing in town.

A small portion of town residents are Jewish, Muslim, Buddhist, or Orthodox, but there are not currently synagogues, mosques, temples, or Orthodox churches in Hudson.
Nevertheless, the town lends its name to the 1907 Hudson Incident – a key event in the Albanian Orthodox Church's formation – in which an Albanian nationalist died in Hudson and was refused burial rites by area Greek Orthodox priests.

The Portuguese Roman Catholics in Hudson hold annual feasts or festivals honoring and celebrating the Holy Ghost and Our Lady of Fátima, known in Portuguese as Festas do Espírito Santo and Festa da Nossa Senhora de Fátima, respectively.
There are three related but distinct festas in Hudson: the Império Mariense, the lmpério Micaelense, and the Lady of Fátima Feast / Festa da Nossa Senhora de Fátima.
The oldest of these is the Império Micaelense festival, which traces its origins to 1914.
Such festivals are a common religious and sociocultural event in the Azores and in Portuguese communities of Azorean descent throughout the United States, Canada, and Brazil.
