People for the Ethical Treatment of Animals (PETA) accused the singer of ignoring cruelty of animals.
It urged her to watch videos of animals being farmed for their pelts.
A spokesman for Madonna - who is set to design a range of clothing for high street chain H&M - said he was unable to comment.
Poorva Joshipura, director of Peta Europe, said: "We encourage anyone who wears fur to watch videos of these animals being electrocuted, caught in traps and skinned alive.
"Thousands of people, including Paris Hilton, have said that the videos changed their minds about wearing fur.
"Chinchillas are shy, intelligent animals who can live for up to 15 years in the wild. Yet on fur farms, these animals are violently killed while fully conscious."
Meanwhile, it has been announced that Madonna is to design a range of clothes for H&M.
The clothing line - including wardrobe staples and accessories - will be launched in March 2007.
H&M said the M by Madonna range would reflect the singer's "timeless, unique and always glamorous style".
It is the second time the 48-year-old pop singer has collaborated with H&M.
The firm also provided an off-stage wardrobe for her Confessions world tour and the singer also designed a tracksuit for H&M.
According to H&M's website, the company does not sell any fur products and only sells leather from sheep, pigs, goats and cattle that have been bred for meat production.
