Jardine's Lookout (Chinese: 渣甸山; Jyutping: zaa1 din1 saan1; Cantonese Yale: ja din saan) is a mountain and a residential area on the Hong Kong Island in Hong Kong. It is located Southeast of the Wan Chai district and South of the Tai Hang area, at an altitude of about 433 metres. Nearby hills include Mount Nicholson, Violet Hill and Mount Butler etc.
It is named after William Jardine, founder of Jardine Matheson. It was from here, in the days of the sailing ships, that a watch was kept for the first glimpse of the sails of the firm's clippers coming from India and London. As soon as a vessel was signalled, a fast whaleboat was sent out to collect Jardines' mails. The correspondence was rushed back to the office so that the directors could have the first possible information on the World's markets.
Due to its scenic view and low population density, it has been considered an upper-class neighborhood in Hong Kong; residences situated there are amongst the most expensive of Hong Kong, and the population mainly consists of highly placed expatriates, government officials and successful businesspeople. In addition, it is also home to numerous Hong Kong socialites, such as Joey Yung. It is also known as the Mid-Levels East.
The area is a localized gated community with large detached houses in private lots and more moderate townhouses. Low-rise and high-rise apartments make up the rest of the community. In 2011, the area had a population of 15,533. This community is conveniently linked with public transportation and well-equipped with facilities. Jardine's Lookout is only a 10-minute drive to Central and 5 to Causeway Bay, where the Cross Harbor Tunnel is located, making travel to the Kowloon side easy.
