Hans Peter Blochwitz (born 28 September 1949) is a German lyric tenor, who is known internationally in opera and concert, especially for singing parts in Mozart operas.

Born in Garmisch-Partenkirchen on 28 September 1949, Blochwitz first studied computer science at the Technische Hochschule Darmstadt[2] and holds a Ph.D. He studied singing from 1975 in Mainz with Elisabeth Fellner Köberle and in Frankfurt with Erna Westenberger and Karlheinz Jarius. He appeared in 1978 in Frankfurt as a soloist in Bach's Mass in B minor, and in 1984 as the Evangelist in Bach's St Matthew Passion at the Altenberger Dom. He made his operatic debut in September 1984 as Lenski in Tchaikovsky's Eugen Onegin at the Frankfurt Opera; he subsequently sang in Brussels, Geneva, Hamburg, Milan, and Vienna, especially as a Mozart singer. When Peter Schreier, a lyric tenor himself, conducted his first production of Mozart's Don Giovanni in 1987, he cast Blochwitz as Don Ottavio. In September 1990 Blochwitz made his debut at the Metropolitan Opera in the same role. In 1991 he appeared as Belmonte in Mozart's Die Entführung aus dem Serail at the Salzburg Festival.
