The market place (Kauppatori) is located in the city centre, right next to the bus station and public transport links, and it is open year round. The market is a meeting place where people stop for a cup of coffee and exchange the latest news.

The City of Porvoo organises a spring and autumn market in the market square and adjacent streets every year, which attracts market traders from all over Finland to come and sell their wares.

The market in the town hall square in Old Porvoo (Raatihuoneentori) is popular with tourists and is open daily during the summer. 

In addition to the markets maintained by the City of Porvoo, there are archipelago-spirited summer markets in Bjurböle and Pellinki.
