The province of Olbia-Tempio (Italian: provincia di Olbia-Tempio; Sardinian: provìntzia de Terranòa-Tèmpiu; Gallurese: pruìncia di Tarranoa-Tèmpiu) was a province in the autonomous region of Sardinia, Italy.

[3] The largest comuni in the province were Olbia (population of 45,366 as of 2001), Tempio Pausania (13,992 as of 2001), Arzachena (12,080 as of 2001) and La Maddalena (11,369 as of 2001).

[5] On 6 May 2012 the regional referendums of Sardinia took place regarding the abolition of certain provinces and a variety of other matters.

[6] Due to this, the former province of Olbia-Tempio was ordered to form a new administrative body or be abolished on 1 March 2013, but this expiry date for constitutional changes was extended to 1 July 2013.

[11] Whilst the Italian government challenged the law,[12] thus stalling its implementation,[13] on March 12, 2022, the Constitutional Court ruled in favor of the Autonomous Region of Sardinia.
