The third Josef Hoop cabinet was the governing body of Liechtenstein from 30 March 1938 to 9 November 1944. It was appointed by Franz Joseph II and chaired by Josef Hoop. The cabinet was formed as a coalition government following the Anschluss of Austria in 1938, and it oversaw the majority of World War II before being succeeded in 1944.

Following the Anschluss of Austria in March 1938, Franz I named his grand-nephew Franz Joseph his regent. The Progressive Citizens' Party and Patriotic Union formed a coalition government formed to prevent government deadlock and help retain Liechtenstein's neutrality, overseen by Franz Joseph II. As a result, the Second Josef Hoop cabinet was succeeded with Josef Hoop continuing as Prime Minister of Liechtenstein.

Starting from 1938, the cabinet was faced with the challenge of pressure to transfer the Ellhorn mountain to Switzerland. Though Hoop was supportive of the transfer, he argued that the country should be fairly compensated for the loss of territory, such as the transfer of Swiss land elsewhere or greater banking cooperation between the two countries. The proposition faced resistance from the residents in Balzers, and was not approved by Franz Joseph II. Also facing unofficial objections from Nazi Germany, Hoop was forced to end the negotiations with Switzerland.

The 1939 Liechtenstein general election was not made public due to the country being under threat from Nazi Germany. It became known as the "silent election" as no voting actually took place; instead, the Progressive Citizen's Party and Patriotic Union used it to assign roughly an equal number of seats to each other in order to prevent the German National Movement in Liechtenstein (VBDL) from gaining any seats in the Landtag. As a result, the Hoop cabinet was now made out of several members of both parties. The government was placed under threat when the VBDL attempted a coup in March 1939, first trying to provoke a intervention from Nazi Germany by burning swastikas, followed by declaring Liechtenstein's annexation into Germany. The leaders were almost immediately arrested and the planned German invasion failed to materialise.

During World War II, Liechtenstein remained neutral. Hoop's government considered non-binding, non-provocative diplomacy to be appropriate towards Nazi Germany, supplemented by courtesy gestures. In 1940, during a lecture in Stuttgart, Hoop showed respect for the German armies. At the same time, the country tied itself as closely as possible to Switzerland during the war in hopes of retaining the country's neutrality. It achieved the de-facto inclusion of Liechtenstein in the Swiss national supply.

At the request of Franz Joseph II on 9 November 1944, the cabinet was dissolved and succeeded by the Fourth Josef Hoop cabinet.
