Joseph Elias Rehal (Arabic: جوزيف الياس رحال; 14 July 1872 – 8 February 1923) was a Lebanese-American merchant and farmer, who was the founder of Joplin, Montana.
Rehal had valuable real estate holdings and is known to have built the first four buildings of the town.
His father, who was engaged in the liquor business, played a major role in the defense of Zahlé during the 1860 civil conflict in Mount Lebanon and Damascus.
He filed a homestead in Chouteau County, Montana and in 1910 founded the village of Joplin, becoming the first postmaster.
They promoted rival parts of the town, which led to uneven and scattered business development.
