Alto Vetro, Apartment building in Grand Canal Dock, Dublin, Ireland.

Alto Vetro is a 16-storey residential tower on the west side of Grand Canal Dock, south of MacMahon Bridge in Dublin. It holds 26 apartments: 24 two-bedroom units, two per floor, and the top two floors form three-bedroom triplex penthouses. A coffee shop and a barber occupy the ground floor. It was built by Sisk for Treasury Holdings and won the RIAI Silver Medal for Housing (2007–2008).

Alto Vetro was built by Sisk for Treasury Holdings, the developer behind Montevetro (now Google Docks) on Barrow Street across the canal basin. A third building in the series, Aqua Vetro, was planned at Tara Street railway station but never started before the company became insolvent. In 2014 receivers appointed by NAMA sold the tower to Kennedy Wilson Europe.

The Royal Institute of the Architects of Ireland awarded Alto Vetro their Silver Medal for Housing in recognition of its architectural excellence.

Alto Vetro stands on the west side of Grand Canal Dock, just south of MacMahon Bridge, with the ground-floor coffee shop and barbers opening onto the waterfront. The canal basin and its bridges link the site on foot toward the city centre, and Barrow Street and Google Docks lie across the water.

Alto Vetro was built by Sisk for Treasury Holdings, the developer behind Google's Dublin headquarters, Montevetro, on Barrow Street across the canal basin. That building was later renamed Google Docks. A third tower in the series, Aqua Vetro, was planned for Tara Street station but never started before the company's insolvency.
