The 1987 Pacific hurricane season was the last year in which the Eastern Pacific Hurricane Center was the primary warning center for tropical cyclones in the eastern Pacific Ocean. The season officially started May 15, 1987, in the eastern Pacific, and June 1, 1987, in the central Pacific, and lasted until November 30, 1987. These dates conventionally delimit the period of each year when the vast majority of tropical cyclones form in the northeastern Pacific Ocean.

Despite there being 20 named systems, five above the average, only four storms directly affected land. Hurricane Eugene was the first Pacific hurricane to make landfall in Mexico in July since the 1954 season and caused three deaths and $142.12 million damage. Tropical Storm Pilar and Hurricane Norma also came close to land, with the former producing record rain in Baja California Sur. The remnants of Hurricanes Ramon and Norma caused rain in the Continental United States, with the former responsible for five traffic-related deaths. Elsewhere, Peke was a central north Pacific hurricane that crossed the International Date Line and became a typhoon of the 1987 Pacific typhoon season.
