Anna Maria Conti (born 1639) was an Italian painter's wife.
She married the failed French immigrant painter Simon Imbert (d. 1658).
The marriage was described as an unhappy one: her spouse reportedly abused her and she suspected him of having poisoned her father.
On 31 January 1659, Giovanna De Grandis was arrested in Rome and imprisoned in the Papal prison at Tor di Nona, which was the beginning of the infamous Spana Prosecution, exposing Gironima Spana's net work of poison dealers in Rome.
Instead, her maid Benedetta Merlini, who had introduced Conti to Crispoldi, was arrested and imprisoned in Tor di Nona, where she was interrogated under torture and testified against Crispoldi.
