Colonel Ely Ould Mohamed Vall (Arabic: إعلي ولد محمد فال I‘lī Wald Muḥammad Fāl; 1953 – 5 May 2017) was a Mauritanian political and military figure.

Following a coup d'état in August 2005, he served as the transitional military leader of Mauritania until 19 April 2007, when he relinquished power to an elected government.

[13] Parliamentary and local elections were held on November 19, 2006, which Ely praised as "the first time Mauritanians have been able to express themselves freely"; he also said that the difficulty of changing the constitution would preserve democracy in the future.

[17] The military under General Mohamed Ould Abdel Aziz seized power again in August 2008, ousting Abdallahi, and a new presidential election was planned.

He stressed, however, that his candidacy was not directed against any particular individual, and he said that his goal, if elected, was "to build a reconciled country that is politically and economically viable and stable".

[18] Official results showed Ely performing poorly in the election, which was held on 18 July 2009, while Abdel Aziz won a majority in the first round.

At a press conference on 30 July, Ely said that the election was merely a means of legitimizing the 2008 coup and that it had effectively reverted the country to the authoritarianism it had experienced under President Taya.
