Walter Thurnherr is a Swiss government official who served as Chancellor of Switzerland from 2016 to 2023. Although he holds a traditionally nonpartisan office, he was elected as a member of the Christian Democratic People's Party (CVP/PDC). When it merged with the Conservative Democratic Party (BDP/PBD) to form The Centre (DM/LC) in 2021, Thurnherr joined the new party.

The Federal Chancellor is the head of the Federal Chancellery of Switzerland, the oldest Swiss federal institution, established at the initiative of Napoleon in 1803. The officeholder acts as the general staff of the seven-member Federal Council. The Chancellor is not a member of the government and the office is not at all comparable to that of the Chancellor of Germany or the Chancellor of Austria.
