A diamond kite, also called an Eddy kite or Malay kite, is a traditional single-line kite with a diamond-shaped planform. It is typically constructed with a frame of two crossed spars, a fabric sail (commonly nylon), and a stabilising tail. It is simple to assemble and fly, performs best in light to moderate winds, and is widely used as a beginner's kite and for recreational flying, particularly by children. One of the most widely recognized kite designs in the Western world, the diamond kite has remained popular for centuries due to its stable and dependable flying characteristics.

Since their introduction to Europe, diamond kites have been employed for a range of practical applications. These have included aerial photography, meteorological observation, and the transmission of long-distance radio signals, reflecting a historical development similar to that of box kites. The historical Eddy kite was invented by William Abner Eddy in the 1890s, drawing inspiration from traditional Javanese bowed kites, which were often referred to as "Malay kites".
