Tertiary can refer to several concepts, most commonly in the context of education and economic activity. In education, tertiary education represents the third level of education, following primary and secondary schooling. This level typically includes universities, colleges, and vocational schools, offering degrees and diplomas in a wide range of subjects. It is where specialized knowledge and skills are acquired.

Economically, tertiary activities, also known as the service sector, are the third broad category of economic production, following primary (extraction of raw materials) and secondary (manufacturing and industry) sectors. This sector encompasses a vast array of industries such as retail, healthcare, education, finance, transportation, and entertainment. The growth of the tertiary sector is often seen as an indicator of economic development, with a larger proportion of the workforce engaged in providing services rather than producing physical goods.

In geology, the Tertiary period is an era that began 66 million years ago and ended 2.58 million years ago. It is part of the Cenozoic Era and is characterized by significant changes in flora and fauna, including the diversification of mammals and birds. It is further subdivided into epochs: Paleogene and Neogene. The Tertiary period witnessed the formation of major mountain ranges and significant shifts in climate.
