Tord Tamerlan Teodor Thorell (3 May 1830 – 22 December 1901) was a Swedish arachnologist.
Thorell studied spiders with Giacomo Doria at the Museo Civico di Storia Naturale de Genoa. He corresponded with other arachnologists, such as Octavius Pickard-Cambridge, Eugène Simon and Thomas Workman.
He described more than 1,000 spider species during his time from the 1850 to 1900.
Thorell wrote: On European Spiders (1869) and Synonym of European Spiders (1870-73).
The Orb-weaver spider genus Thorellina and the jumping spider genus Thorelliola are named after him, as well as about 30 species of spiders:
