A burr puzzle is an interlocking puzzle consisting of notched sticks, combined to make one three-dimensional, usually symmetrical unit. These puzzles are traditionally made of wood, but versions made of plastic or metal can also be found. Quality burr puzzles are usually precision-made for easy sliding and accurate fitting of the pieces. In recent years the definition of "burr" is expanding, as puzzle designers use this name for puzzles not necessarily of stick-based pieces.

Flag as Inappropriate. A burr puzzle with no internal voids when assembled is called a solid burr. On 1979, the American designer and craftsman Stewart Coffin found a level-3 puzzle. These burrs can be taken apart directly by removing a piece or some pieces in one move. In 1985, Bill Cutler found a level-5 burr and shortly afterwards a level-7 burr was found by the Israeli Philippe Dubois. In 1990, Cutler completed the final part of his analysis and found that the highest possible level using notchable pieces is 5, and 139 of those puzzles exist.

Most often they are known as burr puzzles, but also are known as Chinese puzzles, Chinese cross puzzles, interlocking puzzles and notched stick puzzles. The first written evidence of burr puzzles trace to the early 19th century, but it is assumed that they were known in Europe and Asia before. The most common types of burr puzzles consist of at least three notched rods that intersect each other at right angles and which are arranged so that in the inside core there is no empty space.
