Kauppakeskus Viiri is a shopping mall in the southeast part of Klaukkala, Finland. It is the largest shopping centre in the Nurmijärvi municipality.
The mall is divided into Big Viiri (Isoviiri) and Little Viiri (Pikkuviiri). In the spring, the Viiri Fair (Viirin Messut) is held annually in the shopping center. The fair has companies from the shopping center, as well as other stakeholders and sports clubs.
An extension, including a Prismahypermarket, and a new market were planned for the mall. These were to be realized with the construction of the Viirinlaakso area, but HOK-Elanto withdrew from the project and moved Klaukkala's old S-market to a nearby retail space.
