Stewart Ryrie, Junior (1812—1882) was a Scottish-born Australian pastoralist, surveyor and settler colonist of the Monaro district of New South Wales, Australia.

He is associated with early colonial settlement of the Cooma and Jindabyne areas, and the exploration and survey of the Snowy Mountains.

[3] Ryrie was one of the first settlers to explore and survey what is now known as the Snowy Mountains and the adjoining area that is now part of East Gippsland in Victoria.

In December 1839, Deputy Surveyor-General, Samuel Augustus Perry, asked Ryrie to make a 'comprehensive examination of country which has not yet come under regular survey’.

Ryrie made four journeys, during which he drew topographical views of the mountain ranges, some in ink but most in pencil.

[4][5] On 15 February 1840, his party crossed the Crackenback River and climbed the Ramshead Range, to where Kosciuszko Chalet stands today, at Charlottes Pass.

Ryrie was one of the first settlers to sight Mount Kosciuszko—the highest point in mainland Australia—from so near, but missed the opportunity to reach its summit, some weeks before Count Strzelecki ascended and named the mountain, on 5 March 1840.

[4] In April 1840, Ryrie, accompanied by an Aboriginal guide and three soldiers, came across Buchan Caves, in the course of a survey of the area.

By the late 1850s, his brother, Donald Ryrie (1810—1888), also seems to have been residing in the Jindabyne area, remaining there until his death.

Ryrie retained 187 acres on the river bank, and he continued to reside in the Monaro region until 1873.

[29] In 1871, Ryrie bought a property of 40,000 acres (16,188 ha) known as 'Coodra Vale', on the Goodradigbee River—then also known as the 'Little River'— in the area now known as Wee Jasper, near Yass.

[39] A sketchbook, in which he made twenty-one drawings of the mountains in 1840, is held in the collection of the State Library of New South Wales.
