The Club Olympique des Transports (Arabic: النادي الأولمبي للنقل), often referred to as COT or Ennakel is a Tunisian football club based in the city of Tunis.

The club was founded in 1945, the team plays in blue and black colors.

The club gold era was the 70s when coach Hmid Dhib had built a tea.

But, like all districts clubs, the club installed in Mellassine, a popular district of Tunis, was unable to resist the deman and has plummeted in three years to end up in the fourth division in 2007–2008 before rising again to CLP-3, and reaching the quarter-finals of the President Cup this year.

It was in July 1945 that the ancestor of the COT, En-Najah Sports was created through a group.
