The force defines misogyny hate crime as: "Incidents against women that are motivated by an attitude of a man towards a woman and includes behaviour targeted towards a woman by men simply because they are a woman."
The classification now means people can report incidents which might not be considered to be a crime and the police will investigate.
Nottingham Women's Centre has been helping train call centre, force control staff and officers on the beat to recognise misogynistic hate crime and ways to tackle it.
These officers will also examine if and how a victim can be supported or if anything can be done to help prevent them being targeted again.
Domestic abuse will not be recorded as a misogyny hate crime because it has its own procedure, the force said.
Melanie Jeffs, centre manager at Nottingham Women's Centre, said: "We're pleased to see Nottinghamshire Police recognise the breadth of violence and intimidation that women experience on a daily basis in our communities."
She added: "Recording this as a hate crime will give us a detailed picture of how often, when and where it is happening. It has been very difficult to build that picture before but we will now get detailed data to analyse.
"Showing that the police take it seriously will also give people the confidence to come forward and report offences."
