The Mount Washington Auto Road Bicycle Hillclimb is an annual American cycle racing event held in New Hampshire.

The event raises money for the Tin Mountain Conservation Center, which promotes appreciation of the environment.

In August of each year, up to six hundred riders take part in the race which centers around a 7.6 mile (12.2 km) climb to the top of New Hampshire's Mount Washington—the highest peak in New England.
