Diego Della Valle (born 30 December 1953) is an Italian businessman best known as the chairman of the leather goods company Tod's.

[10] In 1993, Della Valle joined forces with Montezemolo and Paolo Borgomanero on reviving the Acqua di Parma brand.

[12] In 1999, Della Valle raised his stake in British shoemaker Church's to 9.5 percent, setting off the speculation about a takeover; he ultimately decided against bidding against Prada which ended up acquiring the company.

[15] In 2004, Della Valle and his brother Andrea took a 40.6 percent stake in eyewear company Marcolin through their holdings.

[2] Around 2008, Della Valle and Montezemolo started working on the launch of high-speed train company Nuovo Trasporto Viaggiatori.

[16] Between 2009 and 2010, Della Valle increased his stake in luxury department store operator Saks, Inc. just above 19 percent, becoming the company's largest shareholder and sending its shares to a two-year high.

[25] In 2024, Della Valle lost a long-running battle with French tax authorities who had investigated the company's odd accounting practices during its controversial acquisition of Roger Vivier resulting in "ambiguous dealing with shareholders" amidst accusations that the family had personally enriched themselves at the expense of shareholders.

Despite opposition from Tod's minority shareholders, the company paid royalties to the Della Valles amounting to €52m from 2004 to 2015, personally enriching the executives.

In 1993, Della Valle supported and financed Silvio Berlusconi’s populist Pole of Freedoms coalition,[32] but soon bowed out, citing differences in values.

[39][37] In 2023, Della Valle suffered a decisive legal defeat with the Consiglio di Stato affirming a 2018 decision that upheld the municipality of Anacapri's 2012 order requiring that Della Valle halt and undo unauthorized expansions including a wellness centre, solarium enlargement, and structural renovations to his Capri residence, a property bound by strict environmental and cultural constraints.
