Piatnytska (St. Paraskeva) Сhurch (Ukrainian: П'ятницька (святої Параскеви) церква) is a functioning church in Chernihiv, Ukraine.

The small Piatnytska Church stood on the public sale area of Chernihiv (Paraskeva Piatnytsia has been long since considered as the trade patron saint).

High dome, numerous stucco moulding, elegant proportions of the church – all these features undoubtedly gave grounds to attribute the building to Ukrainian baroque style of the 17th–18th centuries.

The picture which revealed in front of us was terrible: only ruins remained of Piatnytska Church, rising lonely above the covered with snow wasted grounds of the city destroyed by the fascist invaders."

Everything attested that this monument was of a new architectural style which was formed in Rus' at the end of the 12th century, at the time of «The Word to the Honour of Prince’s Igor Regiment».

Unlike the static forms of previous times buildings, the composition of Piatnytska Church is dynamic, its walls steeply grow upwards with three rows of arches above the main capacity.

In Piatnytska Church everything is built according to one style, unlike Saint Sofia Cathedral of Kyiv, where the composition is developed into an entire symphony.
