The compulsory dance (CD), now called the pattern dance, is a part of the figure skating segment of ice dance competitions in which all the competing couples perform the same standardized steps and holds to the 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 included in International Skating Union (ISU) junior and senior level competition. In June 2010, the ISU replaced the name "compulsory dance" with "pattern dance" for ice dance, and merged it into the short dance (SD) beginning in the 2010–11 figure skating season.

The first CDs were developed during the 1930s by teams from Great Britain, who dominated ice dance for most of the early years after the sport was contested at the 1952 World Championships. The prominence of the CD in ice dance slowly declined, until it was removed and replaced by the SD in 2011, the year that the ISU voted to restructure ice dance competitions by removing the compulsory dance and original dance (OD) and replacing them with the short dance and free dance (FD).

Ice dancers performed the same pattern around the rink once or twice, to the same step sequences and the same standardized tempo. The competitors were then scored based on their execution of the various elements of the dance. The CD allowed the judges to compare the technical skills of each dancer.
