The 2017 North Indian Ocean cyclone season was a below average yet deadly season in the annual cycle of tropical cyclone formation. This season produced only three named storms, of which one only intensified into a very severe cyclonic storm. The North Indian Ocean cyclone season has no official bounds but cyclones tend to form between April and December with the two peaks in May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean. The season began with the formation Cyclone Maarutha on April 15 and ended with the dissipation of a deep depression on December 9.

Cyclonic Storm Maarutha was the first tropical cyclone to make landfall in Myanmar in April. The first tropical cyclone and named storm of the 2017 North Indian Ocean cyclone season, Maarutha was a relatively short-lived and weak system, nonetheless causing notable damage in Myanmar. Maarutha formed from an area of low pressure over the southern Bay of Bengal on April 15. The next morning, RSMC New Delhi upgraded the low-pressure area to a Depression and designated it as BOB 01.
