In legislative procedure, a rider is an additional provision added to a bill or other measure under the consideration by a legislature, having little connection with the subject matter of the bill. Riders are usually created as a tactic to pass a controversial provision that would not pass as its own bill. Occasionally, a controversial provision is attached to a bill not to be passed itself but to prevent the bill from being passed (in which case it is called a wrecking amendment or poison pill).

Rider may refer to:

In theater (and musical performance), a rider is a set of requests or demands that a performer sets as criteria for performance. Types of riders include hospitality and technical.

Rider is a publishing imprint of Ebury Publishing, a Penguin Random House division. The list was started by William Rider & Son in Britain in 1908 when he took over the occult publisher Phillip Wellby. The editorial director of the new list was Ralph Shirley and under his direction, they began to publish titles as varied as the Rider-Waite tarot deck and Bram Stoker's Dracula.

Today the Rider motto is "New Ideas for New Ways of Living" and books and authors on the list reflects this. There are still books on the paranormal, with authors like Raymond Moody and Colin Fry; on astral projection with authors Sylvan Muldoon and Hereward Carrington; and spirituality, with books by the Dalai Lama and Jack Kornfield; but there are also books on current and international affairs by authors as diverse as Nobel Prize-winners Archbishop Desmond Tutu and Shirin Ebadi.

Rider or horseman is an important symbol in heraldry especially in Eastern Europe. It firstly appeared in the 13th century on the old Russian stamps, coins and seals as a symbolic representation of the ruling knyaz. Since the second half of the 15th century the rider striking a dragon with spear became the coat of arms of Russia especially Moscow along with the double-headed eagle. In the 16th century the shield with the rider were placed on the eagle's chest.

Another type of a rider were Lithunian Pahonia/Vytis which appeared nearly at the same time as the Russian one. But main differences are the absence of a dragon, a sword instead of a spear and the direction of the rider (to the right).
