The Konarski Secondary School (1. Liceum Ogólnokształcące w Rzeszowie im. Księdza Stanisława Konarskiego) is a coeducational public secondary school in Rzeszów, Poland. Founded in 1658, it is one of the oldest secondary schools in Poland. Located in the old town in a historic building designed by Tylman van Gameren, it plays an important role in the cultural life of Rzeszów and Subcarpathia Province.

Construction for the building began in 1644 and was funded by Zofia Prudencjanna Ligęza and her brother-in-law Jerzy Sebastian Lubomirski. The school was founded in 1658 but was not established until 1668 by Pope Clement IX. From 1658 until 1784 the school was named as Collegium Resoviense and was run by the Piarists Order. In the 17th and 18th centuries the school was recognized as an important cultural centre, akin to a "semi-university". In 1785, after the First Partition of Poland Austrian authorities removed the school from Piarist control and changed the name to Rzeszów's Ober-Gymnasium. During World War I and Polish-Soviet War teachers and students took part in fighting for the independence of Poland and in 1923 the school was named for Stanisław Konarski. In 1949 the school was reorganised into a four-year high school and in 1964 it became a coeducational high school. The school is part of the Association of Creative Schools and the Club of the Oldest Schools in Poland.

In 1984, the school was awarded the Commander's Cross of the Order of Polonia Restituta.
