Crowdsourcing is seen as a way to acquire knowledge, ideas, and solutions to problems. Literature postulates that it can also be a way to increase employee engagement. However, these findings remain in the sphere of purely theoretical considerations. This article aims at seeking the interdependence between crowdsourcing and employee engagement in public organisations. The subject of the study is to indicate the possibilities of using crowdsourcing to increase employee engagement in municipal offices which use crowdsourcing. Understanding these relationships, public organisations are better able to use the crowdsourcing potential. The data were collected using a survey questionnaire conducted among all 22 identified city offices which make use of crowdsourcing, with an effective sample of 18 municipal offices. A correlation analysis was carried out using a two‐dimensional approach. The research results show that crowdsourcing is positively and moderately related to employee engagement.
