Dutchmans Stern, Mountain summit in Flinders Ranges, Australia.

The Dutchmans Stern is a mountain in the Flinders Ranges, 5 km north-west of Quorn and 25 km north-east of Port Augusta. Its summit reaches 820 m, and since 1987 it has stood within The Dutchmans Stern Conservation Park, where its prominent bluff is considered the park's main feature.

Early settlers named the peak for its resemblance to the stern of a Dutch sailing ship. The British surveyor Matthew Flinders documented this landmark during his exploration of the South Australian coast in the early 1800s.

The name comes from the summit's supposed resemblance to the stern of a Dutch vessel; one account credits early settlers in the vicinity, another the British navigator Matthew Flinders. The bluff is the main feature of The Dutchmans Stern Conservation Park, gazetted in 1987, and the carpark at the park entrance north-east of the summit is where the hike begins.

Two marked trails lead to the summit, offering visitors options based on time and fitness level. The loop route covers more ground while the direct path takes a straighter approach to reach the top.
