Josef Lammerz (1930 – 8 January 2014) was a German composer, choral director and organist.
From 1956 until 1975 he became the organist and Choirmaster at Christ-Koenig-Kirche in Duisburg where he developed a very highly regarded choir, performing major choral works, as well as his own compositions.
He participated in the municipal concerts with the Duisburg Symphony Orchestra at the Mercator-Halle, with works such as Fauré's Requiem, Verdi's Stabat mater, and Liszt's Christus.
Since his retirement in 1989, he has spent long periods in Teulada on the Costa Blanca, Spain, and continues to compose.
A cantata about the great medieval history of Teulada and his outstanding service to the musical life of the city, he was made an honoured citizen, and a street in nearby Xàtiva has been named after him.
