The 2007 Democratic Party leadership election was held on 14 October 2007 in order to elect the first leader of the Democratic Party, the largest political party in Italy at the time. The election was conducted as an open primary, with all Italian citizens aged at least 16 and non-Italian legal residents being eligible to vote. A minimum fee of one euro (initially chosen as five euros, lowered to one euro following direct requests by almost all leadership candidates) was requested to voters in order to take part in the election.
