Santa Monica West Coaster, Steel roller coaster at Pacific Park, Santa Monica Pier, United States.

The Santa Monica West Coaster is a steel roller coaster built by D. H. Morgan Manufacturing at Pacific Park on the Santa Monica Pier. Its 396.2-metre track rises 16.8 metres and runs through two 540-degree helixes, with a small dip after the lift hill and two quick bunny hops between them. A single five-car train carries riders, six per car in three rows of two.

The coaster was designed and built by Morgan Manufacturing and opened to the public on May 25, 1996. It became part of Pacific Park, which developed as a modern amusement area on the pier during the 1990s.

The coaster is part of the Pacific Park amusement area and shapes the visual identity of Santa Monica Pier as one of the region's well-known landmarks. Visitors recognize it from afar and it anchors the entertainment culture of the waterfront.

The single train has five cars, each seating six riders in three rows of two, so capacity is 30 people per cycle. The circuit is 396.2 metres long and climbs to 16.8 metres, with two 540-degree helixes. Riders board at the station on the Santa Monica Pier inside Pacific Park.

The coaster is the only oceanfront roller coaster on the western coast of North America positioned directly above the Pacific Ocean. This creates a special experience as riders see the sea directly below them during the ride.
