The event, pegged for June 5, has been widely shared on social media and has attracted the attention of more than 6,000 people.
Despite the event encouraging those attending to wear masks and remain socially distant, Kent Police says it will not allow the street party to go ahead.
Additionally, the force has vowed to take "proportionate action" against those who "put other people’s lives at risk" by attending.

Event organisers have named the event "Rochester High Street AFTER Lockdown Street Party!" and say it will also be streamed on social media.
With almost 1,000 people planning to attend, those running the event says it aims to help support shops and bars on Rochester's high street following a tough year of lockdowns.
Its Facebook page reads: "Ok so let's do something amazing, let's take it back to when times were simple and community's pulled together.
"Let's have the biggest Street Party Ever!
"After the war nearly every street in England had a party, and after the year we have had its definitely felt like we have been through it!
"The Date is an estimate, but let's all pull together, drag your table and chairs down to the high street and clean off your best crockery and cutlery, candelabras and sunday best and let's celebrate freedom!
"Let's support our amazing High street shops and bars!
"As you are all aware we need to socially distance still, and mask will be needed when you are walking around!
"Will also be streamed on social media!"
Although organisers say they wants to celebrate the end of lockdown, Prime Minister Boris Johnson's current roadmap states the end of all coronavirus restrictions will occur no earlier than June 21.
Only from this date onward will the country have all legal limits on social contact removed.
And even then this date is an estimate which could be postponed by spikes in infection rates.
'Large scale gatherings are not permitted'
A spokesman for Kent Police told KentLive the force was monitoring the event.
Superintendent Rob Marsh, Deputy Commander for north Kent said: "Kent Police has received no formal notification of a street party taking place in Rochester High Street on June 5 2021, but is aware of a possible event being advertised on social media.
"We understand why people want to get together but the current COVID-19 regulations state large scale gatherings are not permitted and anyone considering attending the event is asked to refrain from doing so.
"While COVID-19 restrictions are being eased, people must continue to adhere to the latest Government advice.
"Our officers will work with Medway Council to monitor the details surrounding this event and, should it go ahead, they will not hesitate to take proportionate action against those who put other people’s lives at risk."
