Ahjo Ensemble is a Helsinki-based chamber choir founded in 2013. The choir's mission is to perform versatile choir repertoire at the level of highest quality. During its first years Ahjo Ensemble has focused especially on performing contemporary Finnish choir music and working in several cross-genre productions.

In 2014 Ahjo Ensemble began an ambitious project of performing all the works for mixed choir by the modern Finnish composer Bengt Johansson. The concert series was brought to completion in fall 2017. Ahjo has performed in several Finnish classical music festivals, cooperated with the Helsinki Philharmonic Orchestra and UMO Jazz Orchestra and most recently performed with the Finnish pop producer Pykäri at Flow Festival in August 2017. Ahjo Ensemble was chosen as finalist at the international Harald Andérsen Chamber Choir Competition in 2016, and part of the choir's competition program was broadcast by BBC Radio 3.
