Penfold Park, Public park in Sha Tin District, Hong Kong.

Penfold Park is a public park in Sha Tin District located within the Sha Tin Racecourse grounds. The space features walking trails, artificial lakes, and traditional Chinese pavilions positioned around its perimeter.

The Hong Kong Jockey Club opened the park on 11 May 1979 as Infield Park, built on the centre of the Sha Tin Racecourse. On 17 September 1979 the stewards renamed it for Major-General Bernard Penfold, the club's first general manager (1972–1979), who had overseen the racecourse's construction and was about to retire. The Jockey Club closed it from late July 2007 to April 2008 to build training facilities for the 2008 Olympic equestrian events, and it reopened on 17 January 2009.

In 1997 the Jockey Club asked nearly a hundred of its charity-funded organisations to each paint a carousel-themed mural for Hong Kong's handover; the framed works hang in the pedestrian tunnel linking the park with the racecourse. The park's name honours Major-General Bernard Penfold, the Club's first general manager, who oversaw the racecourse's construction.

The park is closed on Mondays and on Sha Tin Racecourse race days. Outside those times, the only direct public transport to the entrance is minibus 60R, which runs on non-race holidays, and taxis; alternatively, walk from Fo Tan station via the footbridges from Royal Ascot or Jubilee Garden.

The park was requisitioned for the 2008 Olympic equestrian events and rebuilt as isolation stables and a training ground; it reopened to the public on 17 January 2009. The cauldron from those Games stays in the park as a permanent fixture. The Jockey Club later planned to convert the grounds into a retirement park for top racehorses.
