Ingo Metzmacher (born 10 November 1957) is a German conductor and artistic director of the festival KunstFestSpiele Herrenhausen in Hanover.

[12] In February 2007 the opera announced that Metzmacher would step down from his post as DNO's chief conductor in 2008.

[13][5] From 2007 to 2010 he was the chief conductor and artistic director of the Deutsches Symphonie-Orchester Berlin (DSO-Berlin).

However, after reports of disputes over financing and a threatened reduction in the size of the orchestra, in March 2009 Metzmacher announced his early resignation from the DSO-Berlin principal conductorship as of the summer of 2010.

[15][16] His final concerts as the orchestra's principal conductor were in June 2010 in Berlin[17] and in August 2010 at the BBC Proms at the Royal Albert Hall.
