The Treaty of Akhal (Russian: Ахалский договор, Persian: پیمان آخال), also known as Akhal-Khorasan Boundary Convention, was an agreement signed between Qajar Iran and Imperial Russia on 21 September 1881 to mark Iran's official recognition of Khwarazm's (mostly the territory of present-day Turkmenistan) annexation by the Russian Empire.
The title of the treaty is derived from the name of the vast region north of Khorasan where the Turkmen tribe of Tekke lived – Akhal.
