There had been speculation the festival could be held elsewhere following remarks made earlier this year by founder Michael Eavis.
Eavis previously said he "didn't really want to have a year without a festival", and claimed the event could be held somewhere else in 2017 or 2018.
Tickets for next year's event go on sale in October, it has been confirmed.
In a statement on the Glastonbury Festival website, the organisers said: "We will be taking our next fallow year in 2018, in order to give the farm, the village and the festival team the traditional year off.
"There are no plans to hold an event at another location in 2018."
The music festival is held on the Eavis family's Worthy Farm in Somerset, south-west England, and traditionally takes a break every six years so as not to cause damage to the working fields.
The last fallow year was 2012.
In June, Eavis had told the BBC he was "talking to Longleat" as it was his "favourite site" for a new festival.
He had added that hosting it at Worthy Farm meant dealing with 22 different landowners, which "wasn't easy".
Next year's festival will take place from 21 to 25 June, with the first batch of tickets, for those buying coach packages, released on 6 October.
General tickets will be released three days later, at 09:00 BST on 9 October.
Last year's initial release of 120,000 tickets sold out in just over half an hour.
The highlight of the music calendar, this summer Glastonbury featured performances from headliners Adele, Coldplay and Muse, who rocked the Pyramid stage, festooned with a giant lightning bolt in honour of David Bowie.

Figures published by holding company Llandarcy Park (Ospreys) Ltd showed a profit in 2014-15 of £143,498 before exceptional items and interest charges.
Ospreys chief executive Andrew Hore said: "It just shows what can be achieved and we're really proud."
The figures reflect increased revenue from ticket sales and improved funding from the Welsh Rugby Union (WRU).
National Dual Contracts - in which the WRU pays 60% of a player's wage - were introduced during 2014-15, with four Ospreys players signed in that period.
It was also the first year funding for the four Welsh regions was increased from £6.7m to £8.7m following the signing of the Rugby Services Agreement (RSA) after protracted negotiations between Pro Rugby Wales and the WRU.
The profit compares with a net loss of £123,560 in the previous financial year.
Hore added: "A lot of the changes undertaken over the last couple of years actually set us up in a very strong manner for the future, such as changing the RSA and the ability to work more into the community and this kind of thing.
"So if we can continue to grow those community links hopefully we can grow revenues in our rugby base as well."
Ospreys chairman Roger Blyth said: "These figures are the result of the efforts and hard work behind the scenes, across all departments of the organisation.
"We saw a number of new commercial partnerships launched during this period, while the new RSA came into effect, providing a new system to reward national squad contribution more fairly, something which will clearly prove beneficial to the Ospreys given our historic over-contribution to the national cause."
Blyth added there was "cautious optimism" about the future, but work remained to be done, particularly improving the domestic Pro12 to compete with the threat of powerful leagues in England and France.
