Fridolin Anderwert (19 September 1828, in Frauenfeld – 25 December 1880) was a Swiss politician.
He was elected to the Swiss Federal Council on 10 December 1875 and was a member of the council until 25 December 1880. He was affiliated to the Democratic Left, which later developed into the Social-Political Group.
During his time in office, he held the Department of Justice and Police and was Vice-President of the Swiss Confederation in 1880.
On 7 December 1880 he was elected President of the Swiss Confederation for the year 1881. Immediately after the election, a nasty campaign against him broke out in the press, in particular about the eating habits of the obese bachelor, along with rumors that he was a regular visitor to brothels. Drawn by physical exhaustion and severe depression, Anderwert killed himself on Christmas Day 1880 in the "Kleine Schanze", a small park next to the Houses of Parliament. The only published sentence of his farewell letter states: "They want a victim, they shall have it."
