Park West, Business park in west Dublin, Ireland

Park West (Irish: Páirc an Iarthair) is a large business park inside the M50 in west Dublin, in the Dublin 10 and Dublin 12 postal districts. It holds several million square metres of office and retail space, a hotel, a private hospital and three apartment complexes, and the Grand Canal passes through it.

Park West developed as a business park inside the M50 in west Dublin, now housing over 300 companies and more than 10,000 employees, alongside three apartment complexes, a hotel and a private hospital. It falls under Dublin City Council in the Dublin 10 and Dublin 12 postal districts, chiefly the latter, and the Grand Canal runs through it.

Park West is a business park, not a public green space, and its Irish name is given as both Páirc an Iarthair and An Pháirc Thiar. The campus holds public art beyond Angela Conner's Wave, with pieces by Orla de Brí, Fiona Mulholland, Lloyd Le Blanc, Patricia Jorgensen and Martina Galvin placed among the offices.

The campus is reached mainly via the New Nangor Road, Killeen Road and Cloverhill. Bus routes G1 and 151 serve it, and Irish Rail stops at Park West and Cherry Orchard station; express bus 860 runs at peak times as a shuttle for industrial-section workers. The Kylemore Luas Red Line stop is about 3 km away.

Park West is home to Wave by Angela Conner, a 39.3 m (129 ft) wind and water mobile sculpture described as Europe's tallest. Made of polystyrene coated in carbon resin, it is anchored in a 7.6 m pit filled with 9.5 tonnes of lead. Other public art here is by Orla de Brí, Fiona Mulholland, Lloyd Le Blanc, Patricia Jorgensen and Martina Galvin.
