Florida-based Wycliffe Associates made the announcement as it also appealed for more funding to make sure the translations come into fruition.
It announced: "Wycliffe Associates is ready to begin Bible translation in 25 new languages in [an unnamed] region and is currently raising $340,000 of additional funding for those projects."
Donn Hallman from Wycliffe Associates told Premier the region in question could not be named, owing to security concerns facing underground translators there.
The organisation is focused on supporting intensely persecuted Christians in areas where 1,000 languages - representing 280 million people - are without any scriptures.
Through the Scriptures for New Frontiers programme, it supports underground Bible translators by providing translation resources, means for digital distribution and training.
Bruce Smith, President and CEO of Wycliffe Associates, said: "I know many of the translators serving in dangerous places. They are willing to lay down their lives so that their people can have access to God's precious Word.
"The prospect of dying for your faith is no longer a matter of theory for these translators. It is reality. They are truly putting their lives on the line.
"They live with the expectation that one day they will be called upon to sacrifice their lives for the gospel. We don't know - and they don't know - when, or if, that day will come.
"We can only move as quickly as possible to help them translate the Scriptures for their people."
Wycliffe Associates was involved in launching 351 new Bible translation projects around the world last year. It has plans to launch 400 this year.
