Albert Dastre (7 November 1844 – 22 October 1917) was a French physiologist born in Paris.

He studied and worked under Claude Bernard (1813–1878) and Paul Bert (1830–1886) in Paris and attained the chair of general physiology at the Sorbonne in 1886.

One of his better-known assistants was Romanian physiologist Nicolae Paulescu (1869–1931), who was the discoverer of insulin.

He is remembered for his studies of glycosuria and diabetes, as well as for his investigations involving the proteolytic properties of blood.

In 1893, he introduced the term "fibrinolysis", to define a process involving the spontaneous dissolution of blood clots.
