Alsop is due to take up her duties at the start of the 2023/2024 season.
She has conducted NOSPR in 15 concerts since February 2021, including during a tour of Japan.
Commenting on her new role, Alsop said: “I’m thrilled to accept this appointment and excited to continue our already thriving relationship. Our Japan tour last September and our ongoing recording and concert projects are part of a new vision for the 21st-century orchestra."
She added: "Together with NOSPR’s Director, Ewa Bogusz-Moore, I look forward to innovative projects such as Krzysztof Penderecki’s rarely performed opera Black Mask and recording the music of wonderful Polish composers like Grażyna Bacewicz and Agata Zubel. NOSPR’s existing commitment to mentoring the next generations of musicians and conductors also aligns with my personal commitment to the future of classical music."
NOSPR’s General and Programme Director Ewa Bogusz-Moore told the media: “We have had the pleasure of getting to know Marin Alsop over the past two years and we are delighted that she is now joining us as Artistic Director.
"Marin has initiated positive change in the music industry and her work reflects NOSPR’s commitment to identify and address social inequalities.
"Our musicians greatly enjoy working with Marin, whose conducting technique and diligent work ethic ensures musical excellence, and we all look forward to working closely with her over the coming years.”
During her visit to Katowice in March, Alsop was involved with SPLOT–UA, a Polish residency programme for Ukrainian musicians.
In addition to her work with NOSPR, she retains the post of Chief Conductor of the Vienna Radio Symphony Orchestra.
Born in 1956, Alsop is the first woman to serve at the helm of top orchestras in the Americas, Austria and the UK.
Her forthcoming engagements include a highly prestigious appearance with the BBC Symphony Orchestra in the Last Night of the BBC Proms in September.
NOSPR was founded in 1935 in Warsaw by Grzegorz Fitelberg, who led the ensemble until the outbreak of World War II. In 1945, it was given a new lease of life in Katowice.
The orchestra has recorded over 200 CDs for renowned Polish and international labels, including Decca, EMI, Philips, Chandos and Naxos.
Foreign tours have taken it to most European countries, the Americas as well as Japan, Hong Kong, China, Australia, New Zealand, South Korea, Taiwan and the Persian Gulf.
