The Rutford Ice Stream is a large, approximately 290 km long and over 24 km wide ice stream in the West Antarctic Ellsworthland . It flows in a south-easterly direction between the Ellsworth Mountains and the Fletcher Ice Rise in the south-western part of the Filchner-Ronne Ice Shelf . Its catchment area covers 52,000 km². Research shows that the lower part of the ice flow is influenced by the sea ​​tides .

The Advisory Committee on Antarctic Names named it in 1966 after the American geologist Robert Hoxie Rutford (1933-2019), who had led several expeditions of the United States Antarctic Research Program to Antarctica , including the expedition of the University of Minnesota carried out from 1963 to 1964 in the Ellsworth Mountains, and from 1975 to 1977 head of the department for polar programs at the National Science Foundation .
