Dietrich Becker was a German Baroque violinist and composer.
Little is known about Becker's musical education. His first position was as organist at Ahrensberg. In his second position, in the service of the Chapelle Ducale (Ducal Chapel) of the Duke Christian-Ludwig at Celle, he mainly devoted himself to the violin. In 1662 he settled in Hamburg as a violinist in the service of the Conseil de la Ville (City Council) and in 1667 he was named Maître de Chapelle (Chapel Master).
