Nuup Bussii A/S is a bus company in Nuuk, the capital of Greenland, providing public transport services for the city.

As of 2014, Nuup Bussii had 31 employees,[1] operating 16 buses with a distinct yellow color, as well as five other small vehicles.

[1] Prior to the establishment of public services, the ground transport in the city was operated by private entrepreneurs.

[2] The volatility and alleged unreliability of the services prompted the former Nuuk Municipality to regulate the traffic, and establish a public transportation company, overseen by the municipal authorities.

[1] Since 2009 Nuup Bussii provides city transport services in Nuuk for the new Sermersooq municipality,[3] linking the town centre with the outlying districts and neighborhoods[4] of Nuussuaq, Qinngorput, as well as Qernertunnguit in Quassussuup Tungaa.
