The president of the Chamber of Deputies (Italian: presidente della Camera dei deputati) is the speaker of the lower house of the Italian Parliament, the Chamber of Deputies. It is the third highest-ranking office of the Italian Republic, after the president of the Republic and the president of the Senate. Since 14 October 2022, the role has been held by Lorenzo Fontana.

The main function of the president is to ensure that the Chamber of Deputies functions correctly, to guarantee the application of the chamber's rules of procedure, and oversee the proper functioning of its administrative apparatus. The President represents the chamber externally. In the house, the president judges the admissibility of evidence, maintains order and directs the discussion. When a bill is proposed in the chamber, the president decides which permanent committee to allocate it to for development (unless the decision is opposed by a parliamentary group leader or a tenth of the deputies, in which case the allocation is decided by a vote of the chamber).

The task of directing sessions of the chamber belongs to the President. To accomplish this, the President can undertake the following disciplinary actions under article 58ff. of the chamber's regulations: calling a deputy to order, ordering a deputy to leave the chamber, and in serious cases, censuring a deputy and suspending them from the chamber for two to fifteen days.

According to article 55 of the Italian Constitution, the President of the Chamber of Deputies presides over joint sessions of the Italian Parliament (which occur only certain circumstances defined by the constitution: electing the President of the Republic and various groups of judges, and impeaching the president). The President of the Chamber of Deputies must also be consulted by the President of the Republic before the dissolution of Parliament (along with the President of the Senate), according to article 88 of the Constitution.

It is the President of the Chamber of Deputies' job to announce call a joint session of Parliament to elect the President of the Republic, thirty days before the deadline (article 85) or fifteen days after the death or dismissal of the previous President of the Republic (article 86).

Along with the President of the Senate, the President of the Chamber of Deputies appoints the members of some important administrative authorities (like the Antitrust Authority), the administrative council of the National Broadcasting Service, and the presiding council of the Court of Audit.

These posts are appointed by the Presidents of the two houses of Parliament because the way that they are elected tends to ensure that they are impartial consensus figures chosen by both the government and at least part of the opposition.

The President of the Chamber of Deputies is elected by a secret ballot. The chamber's regulations state that the president must be elected by two-thirds of the members of the chamber in the first ballot, or if that fails by a two-thirds majority of voting members of the chamber (excluding abstentions, but including blank ballots) in the second and third ballots, or if that fails by an absolute majority of voting members of the chamber. This election is presided over by one of the vice-presidents of the Chamber of Deputies elected in the previous legislature - whoever was elected first. If no vice-presidents of the previous legislature are present, then the role falls to the vice-presidents of the legislature before that. If none of those are present, then the role falls to the oldest member of the chamber.
