Helsinki Design Week is a multidisciplinary design festival held annually in September, that presents design from a number of fields as well as fashion, architecture and urban culture. Helsinki Design Week 2018 is the largest design festival in the Nordic countries.

Helsinki Design Week presents the new faces and phenomena of design, promotes design internationally in collaboration with various partners and offers city citizens through design a forum to participate in developing and discussing the city and its culture. The festival programme contains around 200 events every year, and includes both events targeted for professionals and the general public. In 2017, the festival boasted about 161,000 visitors.

The festival programme takes place in a variety of event spaces spread throughout the city: from museums to markets, from seminar halls to secret shops. The festival also actively seeks new spaces and ways to explore the city.
