Switzerland recognised the Republic of Estonia on 22 April 1921.
Switzerland never recognised the annexation of Estonia by the Soviet Union and re-recognised the Republic of Estonia on 28 August 1991. Diplomatic relations were restored on 4 September 1991.
After Estonia’s re-independence, the first ambassador named to Switzerland was Toivo Tasa (1995-1999), residing in Vienna. He was followed by Mart Laanemäe (2000-2003), Katrin Saarsalu-Layachi (2003-2009 and 2011-2012) and Gert Antsu (2013-2017). As of 27 November 2018 the Estonian ambassador to the Swiss Confederation is Toomas Kukk, who resides in Vienna.
