Did Salieri poison Mozart?

No. There is no credible evidence that Antonio Salieri poisoned Wolfgang Amadeus Mozart, and the story is essentially a work of fiction that acquired a life of its own.

How Mozart actually died. He died in Vienna in December 1791, aged 35, after an illness lasting a few weeks involving fever, swelling, rash and severe pain. The recorded cause was "severe miliary fever". Modern medical historians have proposed a range of candidates — rheumatic fever, a streptococcal infection leading to kidney failure, trichinosis, and others. No diagnosis is settled, but nothing about the presentation particularly suggests poisoning, and a common contemporary illness is the simplest explanation.

Salieri's actual relationship with Mozart. They were rivals in a competitive court music scene, and there was genuine professional friction — Mozart's letters complain about Italian factions at court. But Salieri was a respected and successful composer who had little to gain. They also collaborated on at least one cantata, Salieri conducted Mozart's work after his death, and he taught Mozart's son Franz Xaver, along with Beethoven, Schubert and Liszt.

Where the rumour came from. Salieri, in mental and physical decline in his final years, is reported to have made a self-accusatory statement — plausibly a symptom of dementia. Rumours circulated in Vienna. Salieri denied it, and two of his attendants signed a statement confirming he never made such a confession in lucid moments.

How it became famous. Pushkin wrote a short play, Mozart and Salieri (1830), dramatising the rumour. Rimsky-Korsakov made it an opera. Peter Shaffer's play Amadeus (1979) and Miloš Forman's 1984 film adaptation cemented it globally.

Shaffer never claimed it was history — the work is explicitly a fantasia about mediocrity confronting genius. Salieri's reputation has been substantially rehabilitated since, with his operas returning to performance.
