The Helsinki Chamber Choir (Helsingin kamarikuoro)
was founded in 1962 as the Finnish Radio Chamber Choir and assumed its current name in 2005. It is currently Finland’s only professional chamber choir.

The choir’s Artistic Director from 2005–2007 was Kimmo Hakola. Since 2007 Nils Schweckendiek has been responsible for the group's artistic planning.

While its wide-ranging repertoire includes music from the Renaissance to the present day, the Helsinki Chamber Choir is particularly highly regarded for its work with new music. The choir regularly commissions new works and has given over 50 world premieres in the seasons since 2005, as well as more than 30 Finnish first performances. The choir appears frequently at major Finnish music festivals and collaborates with orchestras and Baroque and contemporary music ensembles. Recent touring has included concerts in Russia, Estonia and Belgium.

The Helsinki Chamber Choir's concerts are regularly broadcast on radio and television, both nationally and internationally. Particular highlights have been televised performances on the international cultural channel ARTE of Michael Haydn's Requiem in 2006 and Einojuhani Rautavaara's Vigilia in 2013.

The Helsinki Chamber Choir's recording of Magnus Lindberg's Graffiti (with the Finnish Radio Symphony Orchestra and Sakari Oramo) was nominated for a Grammy in the contemporary music category in 2010. During its days as the Finnish Radio Chamber Choir, the group recorded a number of CDs for the Ondine label, including Rautavaara's complete works for mixed a cappella choir. The choir's most recent appearance on CD is in the world premiere recording of Veli-Matti Puumala's opera Anna Liisa (to be released in May 2015). A number of other recordings will appear in the near future.

Since 2012 the Helsinki Chamber Choir has been a member of Tenso, the association of European professional chamber choirs.

The Finnish Radio Chamber Choir’s principal conductors were Harald Andersén, Kaj-Erik Gustafsson, Ilmo Riihimäki, Eric-Olof Söderström and Timo Nuoranne. Alongside Nils Schweckendiek, in recent years the choir has worked with conductors including Kaspars Putnins, Fredrik Malmberg, Eric-Olof Söderström, Andres Mustonen, Olari Elts, Rachid Safir, Tim Brown, Anne Azéma, Aapo Häkkinen, James Wood and Rinaldo Alessandrini.
