The survey, conducted by pollster CBOS for the newspaper Dziennik Gazeta Prawna, found that nearly 53 percent of respondents opposed an increase in the retirement age, while 20 percent supported the idea.
Support was strongest among people aged 18 to 24, with nearly 34 percent favouring a higher retirement age than under current rules.
The lowest level of support was recorded among respondents aged 55 to 64, with only 11 percent backing an increase.
Despite broad public opposition, data from Poland's Social Insurance Institution (ZUS) show that Poles are already retiring later than in previous decades.
In 2004, the average age at which people began drawing pension benefits was 56. By 2024, that figure had risen to 62, according to ZUS.
Poland has one of the lowest retirement ages in the European Union, set at 60 for women and 65 for men.
A study earlier this year by the Polish Economic Institute (PIE) think tank found that the number of people working beyond retirement age is rising, driven in part by demographic changes.
Older workers are most commonly employed in traditional sectors of the economy such as trade, industry, healthcare, education and agriculture, according to the study.
