Campania 2 is one of the 29 constituencies (Italian: circoscrizioni) represented in the Chamber of Deputies, the lower house of the Italian parliament. The constituency currently elects 18 deputies. Its boundaries correspond to those of the provinces of Avellino, Benevento, Caserta and Salerno, within the Campania region. The electoral system uses a parallel voting system, which act as a mixed system, with 3⁄8 of seats allocated using a first-past-the-post electoral system and 5⁄8 using a proportional method, with one round of voting.

The constituency was first established by the Mattarella law on 4 August 1993 and later confirmed by the Calderoli law on 21 December 2005 and by the Rosato law on 3 November 2017. The current borders of the districts were created as a result of the 2020 Italian Constitutional Referendum.
