According to the United States Census Bureau, the township has a total area of 6.9 square miles (18 km²), all of it land.

Ohio Township has four borders, including Franklin Park to the north, Ross Township to the east, Kilbuck Township to the south, and Sewickley Hills to the west.

As reported in the History of Allegheny County, Pennsylvania,[6] Ohio was the third township to be formed in Allegheny County north of the Ohio River, and it was the first subdivision of Pine township. Its creation was begun in December 1802, when a petition was filed in the court of quarter sessions. Gen. John Neville signed this petition. After considerable discussion as to where the boundary line would be created, at the September term of 1803, the court confirmed absolutely a division line which is currently the western boundaries of the current jurisdictions of Pine, McCandless, and Ross townships and Bellevue Borough, including that area of Allegheny County located west of this boundary line and north of the Ohio River as well as including Neville Island.

No event of remarkable interest signaled its early settlement. Being situated on the "Indian side" of the Ohio River, the first Caucasian inhabitants did not appear more than a few years prior to 1800, as this section of the country was not open to settlement until 1792. The first permanent settler to Ohio township was reported as William Richey in 1801. He had been a soldier in Wayne's expedition. While the army was lying at Legionville (near present-day Baden, Pennsylvania), he was sent on some commission to Fort Pitt. The Duff family was first represented by James Duff and his two sons, who crossed the Ohio River in 1799 and located near the river, relocating further inland in 1805. James Moore immigrated from Northumberland County with a large family about the same time. In addition to these, the Crawfords, who settled on Lowrie's Run, have been numerously represented by their descendants, the Gillilands, the Ritchies, Shannons, and others.

Ohio township was later reduced in size by the creation of other townships within its borders: among some of them, Franklin in 1823, Sewickley in 1854, and Kilbuck in 1869. The population in 1860 was 1,350, in 1870 was 685 (after loss of Kilbuck township area), and in 1880 was 737. Mount Nebo United Presbyterian Church was organized June 17, 1838. The land for the church was donated by two local farmers, Hugh Thompson and William Duff.
