Federico Badoer (1519–1593) was a diplomat of the Republic of Venice whose career was derailed in the 1560s by debts and unauthorized diplomacy.
On 28 February 1547, he was sent as an ambassador extraordinary to the court of Duke Guidobaldo II of Urbino to give the republic's condolences on the death of the Duchess Giulia da Varano.
On 24 March 1554, he was named ambassador to the court of Charles V, Holy Roman Emperor, where he arrived in November.
[4] After he defaulted on the many debts he incurred funding his upstart academy, the Venetian Senate ordered his arrest on 19 August 1561, along with his nephews, Alvise, Giustiniano and Giovanni.
On 7 December 1568, a warrant was again issued of his arrest for improper dealings with a foreign prince, Duke Henry II of Brunswick-Wolfenbüttel, who wished to settle in Venice.
On 15 December, the Council confiscated 13,375 scudi and 9,314 ducats that the duke had given Badoer to purchase property on his behalf.
