Hermann Julian Winkler (born 22 April 1963) is a German politician who served as Member of the European Parliament (MEP) from Germany from 2009 until 2019.

In this capacity, he was a member of the Board of Directors of the publicly owned Landesbank Sachsen – at the time the smallest of Germany's Landesbanken – between 2006 and 2007, until its near-collapse and its subsequent sale to LBBW.

[14] In April 2015, he was the first relator of a law proposal for setting up a Union system for supply chain due diligence self-certification of responsible importers of tin, tantalum and tungsten, their ores, and gold originating in conflict-affected and high-risk areas.

[15] In June 2015, Winkler again was one of only two members of the EPP group – this time alongside Remo Sernagiotto – who opposed a tough resolution adopted by the European Parliament, in which the majority of MEPs appealed to the EU to reassess its relations with Russia in the context of the Russo-Ukrainian War.

The painting depicted German Chancellor Angela Merkel standing next to a masked person pointing a rifle at her head and was intended to symbolize the ambiguity of exercise of power.
