The following is a list of notable roller skaters and inline skaters.
 The list is sorted by roller skating disciplines (inline speed skating, roller inline hockey, downhill, artistic roller skating), gender and competing nationality.
 Note that some definitions of roller skating include inline, while others intend to specify quad skates.
Compulsory dances, now called pattern dance in ice dancing, are a part of ice dancing and artistic roller skating in which all the couples or solo dancers perform the same standardized steps and holds to music of a specified tempo and genre.
 One or more compulsory dances were usually skated as the first phase of ice dancing competitions.
 The 2009-10 season was the final season in which the segment was competed in ISU junior and senior level competition.
 In June 2010, the International Skating Union replaced the name "compulsory dance" with "pattern dance" for ice dancing, and merged it into the short dance beginning in the 2010–2011 figure skating season.
 Compulsory dances are still skated in international roller skating competitions, however as in ice skating, a new section called the Style Dance was introduced from the 2015/16 season alongside the standard compulsory dances and freedance categories.
 The style dance is very similar in structure to the short dance on ice.

Roller skating is the traveling on surfaces with roller skates.
 It is a form of recreational activity as well as a sport, and can also be a form of transportation.
 Skates generally come in three basic varieties: quad roller skates, inline skates or blades and tri-skates, though some have experimented with a single-wheeled "quintessence skate" or other variations on the basic skate design.
 In America, this hobby was most popular, first between 1935 and the early 1960s and then in the 1970s, when polyurethane wheels were created and "Disco" oriented roller rinks were the rage and then again in the 1990s when in-line outdoor roller skating, thanks to the improvement made to inline roller skates in 1981 by Scott Olson, took hold.
