Arrow Dynamics was an American manufacturing and engineering company that specialized in designing and building amusement park rides, especially roller coasters. Based in Clearfield, Utah, the company was the successor to Arrow Development (1946–1981) and Arrow Huss (1981–1986), which were responsible for several influential advancements in the amusement and theme park industries. Among the most significant was tubular steel track, which provided a smoother ride than the railroad style rails commonly used prior to the 1960s on wooden roller coasters. The Matterhorn Bobsleds at Disneyland, built in 1959, was Arrow's first roller coaster project.

In 1975, Arrow Development introduced the first corkscrew style track Corkscrew, at Knott's Berry Farm that sent riders through a series of corkscrews. Arrow created several other "firsts" over the years, introducing the first suspended roller coaster in almost a century, The Bat, in 1981, and the first "hypercoaster", Magnum XL-200, which opened in 1989. They built the first 4th Dimension roller coaster, X2, which was designed by Alan Schilke in 2002.

Arrow Development's ownership changed three times between the 1950s and 1980s. Arrow Dynamics would eventually survive two bankruptcies and spin off a sister company, Fabriweld, primarily to build track, by 1988. Arrow Dynamics eventually closed on December 3, 2001. S&S Worldwide purchased part of Arrow's remaining assets on October 28, 2002, and the remainder of the company was dissolved. In 2012, Sansei Yusoki Co. of Osaka, Japan, acquired a 77.3% interest in S&S - Arrow.

Arrow Dynamics' forerunner, Arrow Development, was founded in 1946 when Ed Morgan, Karl Bacon, Bill Hardiman, and Angus "Andy" Anderson, started a machine shop in Mountain View, California. They started out selling used machine tools, building truck parts, and repairing cars until about 1950 when they built their first merry-go-rounds for San Jose's Alum Rock Park.

In 1953, they contacted Walt Disney, who was just beginning to plan a new type of amusement park in California. Disney hired the company to help design and build the vehicles for Mr. Toad's Wild Ride. They would eventually design and build the ride systems for many of Disneyland's original and early rides, including Mad Tea Party, King Arthur Carrousel, Casey Jr. Circus Train, and Snow White's Scary Adventures. Disney continued to use Arrow as Disneyland expanded. Arrow designed and built Dumbo the Flying Elephant, Autopia, and Alice in Wonderland in coming years as well as upgrading and renovating the King Arthur Carrousel.

In 1959, Arrow Development designed what was to be their first of many roller coasters, the Matterhorn Bobsleds at Disneyland in Anaheim, California. Built in conjunction with WED Imagineering, the ride was the first modern tubular steel tracked roller coaster.

After construction of the Matterhorn, Disney bought a third of Arrow Development in an effort to keep them viable and at least partially in-house. Arrow had already developed rides for other customers, and had orders for more, so they moved into a larger plant in Mountain View. At the new location, Arrow developed vehicles, flumes and tracks for It's a Small World, Pirates of the Caribbean, Adventure Thru Inner Space, and the Haunted Mansion.

Arrow developed the modern log flume ride, eventually installing over 50 around the world, beginning with El Aserradero at Six Flags Over Texas in 1963. In the 1970s, the company perfected and brought back the looping roller coaster.
