St Kilda Beach is a beach located in St Kilda, Port Phillip, Victoria, Australia, 6 kilometres (3.7 mi) south from the Melbourne city centre. It is Melbourne's most famous beach. The beach is a sandy beach about 700 metres (2,300 ft) long between St Kilda Marina and St Kilda Harbour along St Kilda Esplanade and Jacka Boulavard. It is located at the north-east corner of Port Phillip and is protected from ocean swell, though still affected by strong westerly winds. With Port Phillip Bay being open to the sea, St Kilda Beach is subject to regular tides.
The St Kilda Pier is another landmark. The pier is terminated by the St Kilda Pavilion, an eccentric Edwardian building in the mould of English pier pavilions which is considered of high cultural importance to Melburnians. It was recently reconstructed and listed on the Victorian Heritage Register after burning down. The pier has a long breakwater which shelters St Kilda Harbour and hosts a Fairy Penguin colony.
