Taieri College, formerly called The Taieri High School and, prior to 1956, the Mosgiel District High School, is a co-educational state school in Mosgiel, Dunedin, New Zealand.
In 2003 a review of the schools on the Taieri Plains by the New Zealand Ministry of Education proposed that the high school would merge with Mosgiel Intermediate School (est. 1973) to become Taieri College from 2004. Because of this merger, ready-made classrooms were built for the intermediate students, as well as a second technology block. The roll expanded to over 800 in its first year, compared with the former high school's number of under 650 students, and now has 1090 students in 2018.

Classrooms
In 2005 it was announced that more classrooms were to be built as well as refurbishment of present classroom blocks. In 2006 the roll exceeded 1000, making it one of Otago's largest schools. Zoning has been proposed to cap or maintain future numbers, as classroom space is becoming limited, even though a new two-storey classroom block, G block, has been completed.
Enrolment
As of July 2026, the school has roll of 1,198 students, of which 198 (16.5%) identify as Māori.
As of 2026, the school has an Equity Index of 459, placing it amongst schools whose students have average socioeconomic barriers to achievement (roughly equivalent to deciles 5 and 6 under the former socio-economic decile system).
