Worthing Pier is a public pleasure pier in Worthing, West Sussex, England. Designed by Sir Robert Rawlinson, it was opened on 12 April 1862 and remains open to the public. The pier originally was a simple promenade deck 960 ft (290 m) long and 15 ft (4.6 m) wide. In 1888 the pier was upgraded with the width increased to 30 ft (9.1 m) and the pier head increased to 105 ft (32 m) for a 650-seat pavilion to be built. It is a Grade II listed building structure.

The pier has been named Pier of the Year by the National Piers Society on two occasions, first in 2006 and again in 2019.

By 1894 a steam ship began operation between Worthing Pier and the Chain Pier in Brighton, ten miles to the east. Over the Easter weekend that year, four-year-old Archie Miles became separated from his promenading family and managed to unwittingly stow away on . This set off a police hunt and he was only reunited with his parents after a night in the workhouse at Brighton and a telegram to his grandparents in Mayfield.

The first moving picture show in Worthing was seen on the pier on 31 August 1896 and is commemorated today by a blue plaque.

In March 1913, on Easter Monday, the pier was damaged in a storm, with only the southern end remaining, completely cut off from land. Later, it was affectionately named 'Easter Island'. A rebuilt pier was opened on 29 May 1914.

In September 1933 the pier and all but the northern pavilion were destroyed by fire. In 1935 the remodelled Streamline Moderne pier was opened, and it is this that remains today.

Worthing Pier was sectioned in 1940 for fear of German invasion after the British retreat at Dunkirk. Army engineers used explosive to blow a 120ft. hole by in the pier to prevent it from being used as a possible landing stage in the event of an invasion.

The pier is owned by Worthing Borough Council (formerly Worthing Corporation).
