Vaporetto is a waterbus operation. It has a set of 19 scheduled lines that serves locales within Venice, Italy, and travels between Venice and nearby islands, e.g., Murano and Lido. (The name, vaporetto, also serves as the appellation for a single such craft, vaporetti being the plural version of the name.) The natives used to call the Vaporetto Batèo. The waterbus line is operated by Azienda Consorzio Trasporti Veneziano (ACTV), the Venetian public transportation system. The system is necessary in Venice as the deep canals prohibit the building of underground railways, and there is no space for overground trains, leaving the canals as the only viable rapid transport system. Most vaporetti have disabled access.

It has twenty-four-hour scheduled service, with frequency varying by the line. Line 1 serves the Grand Canal. Several lines are limited to the summer season, April to October.

ACTV sells 12, 24, 36, 48 and 72 hour passes as well as single-journey tickets and 7-day passes.
