Neithard Resa (born 1 September 1950) is a German violist and former member of the Berlin Philharmonic.
Resa was born in Berlin as the son of a merchant and started playing the violin at the age of seven.
He studied violin at the Musikhochschule Berlin in 1969, first with Michel Schwalbé, from 1971 privately with Marie-Luise von Kleist König and in 1972 with Max Rostal.
In 1977, he went to the USA on a scholarship from the German Academic Exchange Service, where he was taught in Philadelphia by the violist Michael Tree of the Guarneri String Quartet.
As successor to Giusto Cappone, Resa became principal viola with the Berliner Philharmoniker from 24 August 1978 to 2010, where he remained until his retirement.
