Taxis-Bordogna-Valnigra is the name of the descendants of Elisabeth von Taxis († 1518) and her husband Bonus von Bordogna. Elisabeth Taxis was a sister of the Brussels Postmaster General Johann Baptista of Taxis (1470–1541), the ancestor of the Princely House of Thurn and Taxis.
The House of Taxis-Bordogna-Valnigra was first mentioned in documents in 1148 with Angelbertus de Fondra, and goes back to Bonazolus Fondra de Bordogna (c. 1330).
Bonus von Bordogna worked with his in-laws in the Taxis family's postal system and took over the post office in Trento from his brother-in-law David von Taxis. The next iteration of the family's surname was Bordogna von Taxis. Charles VI, Holy Roman Emperor elevated the Bordogna von Taxis family to the rank of barons and then later to counts under the surname Taxis-Bordogna-Valnigra. The baronial branch held the Lieutenant Postmaster General position in Trento and the Adige and the counts held the Lieutenant Postmaster General position in Bolzano.
The descendants of Lamoral, Baron Taxis di Bordogna e Valnigra (1900–1966) from his marriage to Princess Theresia Christiane of Saxe-Coburg and Gotha (1902–1990), daughter of Prince August Leopold of Saxe-Coburg and Gotha and his wife Archduchess Karoline Marie of Austria, are known by the family name Tasso de Saxe-Coburgo e Bragança.
