The Order of the Niger (OON) is the second highest national award in Nigeria.

The two highest honours, the Grand Commander of the Order of the Federal Republic and Grand Commander in the Order of the Niger, are awarded to the president and vice-president respectively.

The presiding judge in the Supreme Court and the chairman of the Senate are qualitative and ex officio Grand Commander of the Order of the Niger.

Similarly, there are post-nominal letters for members of the Order of the Niger.

The ribbon of the latter division has a small red line in the middle.
