Peter Bleser (born 23 July 1952) is a German politician of the Christian Democratic Union (CDU) who served as a member of the Bundestag from 1990 until 2021, representing Mosel/Rhein-Hunsrück.

In 2011, Bleser succeeded Julia Klöckner[1] as Parliamentary State secretary at the Federal Ministry of Food, Agriculture and Consumer Protection under minister Ilse Aigner (2008–2013) in the second cabinet of Chancellor Angela Merkel.

Shortly after his re-election in 2017, Bleser had his parliamentary immunity lifted when prosecutors launched an investigation against him for suspected breach of trust and party financing laws.

According to investigators, Bleser was alleged to have accepted some €56,000 ($66,000) in illegal donations from Werner Mauss between 2004 and 2015, first as the chairman of the CDU's district association in Cochem-Zell and then as the party's treasurer in Rhineland-Palatinate.
