Reinhard Hans Bütikofer (born 26 January 1953) is a German politician who served as a member of the European Parliament from 2009 to 2024.

Bütikofer was active in the student's movement and one of the "K-gruppen", the Maoist Communist League of West Germany (Kommunistischer Bund Westdeutschland; KBW).

After a year of parental leave, in 1997 Bütikofer became co-chairman of the Green Party in Baden-Württemberg, alongside Monika Schnaitmann.

[8] In 2010, Bütikofer characterized his party as representing “a certain lifestyle,” noting that, mostly urbanized, many belong to the professions and are politically and socially engaged.

[9] Under Bütikofer’s leadership, a two-year-long effort to negotiate a revised immigration law was abandoned by the Green Party in 2004, citing concerns about, among other things, that any regulations allowing easier detentions or expulsions of terror suspects would subvert Germany's civil rights protections.

[10] When the European Commission issued a strategy paper in 2010 which proposed pursuing more bilateral trade agreements and investing in infrastructure in Africa as a means to increase alternative sources of rare earth metals, hoping to break China’s dominance of the market for the strategic minerals, Bütikofer demanded an “innovative industrial policy that reduces the use of resources” instead.

[11] When German Chancellor Gerhard Schröder announced in 2005 his intentions to lift an arms embargo on China that had been in place since the crackdown on student-led opposition demonstrators near Tiananmen Square in Beijing in 1989, Bütikofer opposed the plan and instead called for a joint approach together with the United States.

[13] Also in 2020, he was one of 40 fellow Members of the European Parliament from five political groups who called for EU member states and the Commission to cut European public funding for Chinese 5G vendors Huawei and ZTE in a letter, arguing the two are "high-risk" companies that pose a security threat to network security in Europe.

"[16] In addition, Bütikofer served on the board of Europa-Union Deutschland, the German branch of the Union of European Federalists (UEF), Aspen Institute Berlin, and German-Chinese Dialogue Forum.
