A mega ramp, or megaramp, is a large vert ramp structure, often used in skateboarding and freestyle BMX. First built in the 1990s and 2000s, megaramps are twice or more the size of earlier vert ramps.

MegaRamp (styled with title caps and without a space) is the name of a mega ramp event organization and promotion company.

Contemporary structures are generally constructed of metal scaffold with a wood surface topped with Skatelite, and consist of two or three sections. The most common ramp setup, used as well by MegaRamp, is a sequence of three mega ramp sections; a roll-in, a gap jump, and a vert quarter pipe. Vert half-pipe mega ramps have been built, but they are uncommon.

The roll-in section consists of a single or multiple roll-ins that drop from 12m (40') or higher up. The roll-in allows athletes to gain the speed needed to tackle the other sections of the ramp.

The second section can be a quarter pipe, but is more often a gap jump with a distance of 7.5m (25') to 21m (70') between the launch section and the landing section, which is sloped forward to decrease the impact.

The third section is almost invariably a quarter pipe. The quarter pipes can be 5.4m (18') or greater in height and serve as either a speed brake, or as another launch point from which the athlete sails directly vertical into the air off the top lip of the ramp, before falling back down and re-landing on the quarter pipe.

Other additions and modifications have been tried on mega ramps, such as the tall flatbox with a rainbow rail that was added to the Point X mega ramp.

The total length of these structures varies from about 60m (200') to 108m (360').
