The Logan River is the name of two distinct rivers: one in Queensland, Australia, and another in Utah-Idaho, United States.

Logan River in Queensland, Australia

The Logan River is a significant waterway in South East Queensland, running for 184 kilometers. Its source is below Mount Ernest in the Scenic Rim, near the border between Queensland and New South Wales. The river travels through national parks, including Mount Barney National Park, flows north through regions such as the Scenic Rim, Logan City, and Gold Coast, and finally empties into Moreton Bay east of Alberton. Its catchment area supports a mix of rural, urban, and agricultural landscapes and includes notable tributaries such as the Albert River.

Logan River in Utah-Idaho, United States

The Logan River in the US is approximately 54 miles (87 km) long and originates in the Bear River Mountains near the Utah-Idaho border. It flows southwest through Logan Canyon, passes through the city of Logan in Cache Valley, and joins the Little Bear River west of Logan, Utah. This river is notable for its scenic canyon, recreational significance, and its dams at the mouth of Logan Canyon for hydroelectric power.

Both rivers are ecologically, culturally, and economically important to their respective regions.
