The 1950 Pacific typhoon season has no official bounds; it ran year-round in 1950, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

The scope of this article is limited to the Pacific Ocean, north of the equator and west of the International Date Line. Storms that form east of the date line and north of the equator are called hurricanes; see 1950 Pacific hurricane season. This would be the first season that Fleet Weather Center in Guam, predecessor agency to Joint Typhoon Warning Center, would take most of the responsibility in the basin, including naming the storms.^[1] Before this season, the storms are identified and named by the United States Armed Services, and these names are taken from the list that USAS publicly adopted before the 1945 season started.^[2]^[3]
