Which State Is Closer to the Pacific: Nevada or Ohio?

Nevada—by a continent.

• Nevada is a Western state bordering California (Pacific coastline) to the west. Its western edge is ~50 miles (80 km) from the Pacific at the closest point (near Lake Tahoe → Sacramento → SF Bay).
• Ohio is a Midwestern, landlocked state ~2,000 miles (3,200 km) from the Pacific. It borders Lake Erie (Great Lakes/St. Lawrence watershed → Atlantic).

Nevada's rivers (Humboldt, Truckee, Carson) drain into the Great Basin (endemic) or Pyramid/Walker Lakes—not the Pacific. But geographically, Nevada is in the Pacific watershed region; Ohio is firmly Atlantic/Arctic watershed.
