Eucnemesaurus was named by Van Hoepen (1920). Its type is Eucnemesaurus fortis.
It was synonymized subjectively with Euskelosaurus by Heerden (1979) and Cooper (1981); it was considered a nomen dubium by Galton and Upchurch (2004).
It was assigned to Plateosauridae by Van Hoepen (1920), Haughton (1924) and Nopcsa (1928); to Prosauropoda by Kuhn (1939); to Saurischia by Huene (1940); to Melanorosauridae by Huene (1941), Haughton and Brink (1954), Romer (1956), Romer (1966), Charig (1967) and Steel (1970); to Plateosauria by Smith and Pol (2007) and Apaldetti et al. (2011); to Massopoda by Otero and Pol (2013); and to Riojasauridae by Yates (2007), Yates (2010), Novas et al. (2011) and McPhee et al. (2015).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| B. W. McPhee et al. 2015 | presence of a large posterior proximal tubercle on the femoral head (although the phylogenetic expression of this character has recently come in doubt; see below); proximally abrupt lesser trochanter that is taller than its basal width; fourth trochanter rounded in profile and obliquely oriented so that the proximal half is more medially set than the distal half. |
