The Principality of Najran was a state that existed in the Arabian peninsula from 1633 to 1934.

It originated as an Islamic ecclesiastic principality under Yemeni suzerainty in 1633, although it later came under Ottoman influence.

[5] The Mutawakkilite Kingdom of Yemen also had ambitions in Najran, and thus attempted its own conquest in 1924.

[1] In the winter of 1931/1932, Yemeni forces once again attempted to take Najran, but were expelled by the Saudis in 1932.

[7] In 1934, following the Saudi-Yemeni War, Najran's independence definitively ended when Yemen renounced its claims to Najran and the principality was annexed into Saudi Arabia.
