Coolham is a hamlet in the Horsham District of West Sussex, England. It is located at the crossroads of the A272 and B2139 roads 2.8 miles (4.6 km) southeast of Billingshurst. At the crossroads is an old timber-framed inn, the Selsey Arms, formerly the Duke's Head, and before that The King of Prussia.

During World War II there was an advance landing ground nearby, used to support the D-Day landings. This was only in use for about eighteen months, and had almost no permanent buildings. The airmen lived under canvas. Both Polish and British airmen were stationed there, and there is a monument outside the Selsey Arms which lists the names of those who died. The land has long since been reclaimed for agricultural purposes, but there is still a footpath around the field, with trees planted at intervals to commemorate the dead airmen. Each tree has a name plaque attached.

There was once a prominent Quaker community in Coolham, and the "Blue Idol" meeting house, a lovely old timber-framed building, still exists. William Penn, who earlier had founded Pennsylvania in the USA, was closely involved in its establishment, and is believed to have worshipped there. The local junior school was founded as the Coolham British School (later Coolham Primary School) in 1889 by the Quakers. In the mid-twentieth century it moved to its present site, where it is known as the William Penn Primary School.
