Bob Loughman Weibur[1] (born 8 March 1961)[2] is a Vanuatuan politician who served as Prime Minister of the Republic of Vanuatu between April 2020 and November 2022.

During the 2020 United Nations General Assembly address, Loughman called out Indonesia over human rights violations in the region, prompting a response from Indonesian diplomats who labeled his speech as having an "excessive and unhealthy obsession" with the cause of West Papua and accused Loughman of meddling in Indonesia's internal affairs.

[9][10] On 1 June 2021, the opposition filed a no-confidence vote against Loughman over alleged excessive spending in the situation of national crisis due to the COVID-19 pandemic in Vanuatu and the impact of Cyclone Harold last year, both things which have negatively impacted Vanuatu's economy.

[13] On 18 June 2021, Saksak confirmed that 19 government MPs including Loughman had lost their seats.

[16] A new no-confidence motion was avoided in August 2022 by Vanuatu's president dissolving Parliament at short notice.
