One million (1,000,000) or one thousand thousand is the natural number following 999,999 and preceding 1,000,001. The word is derived from the early Italian millione (milione in modern Italian), from mille, "thousand", plus the augmentative suffix -one. It is commonly abbreviated as m or M; further MM ("thousand thousands", from Latin "Mille"; not to be confused with the Roman numeral MM = 2,000), mm, or mn in financial contexts.

Million+, formerly known as the Campaign for Mainstream Universities (CMU) is a university think-tank, seeking to solve complex problems in the higher education sector. Million+ (styled million+) is funded by contributions from its members, currently 17 UK universities incorporating post-1992 and university colleges. Many have long histories as colleges and polytechnics.
