It was due to take place from July 28 to August 4 this year, but has now been pushed back due to the Covid-19 pandemic.
In a statement, organisers said they wanted to make a decision in a timely manner - the festival is now due to take place from September 19 to 26, subject to HSE guidlines.
However, organisers say it will give them more time to create even better events for everyone involved.
"As the situation with Covid-19 continues, Cork LGBT+ Pride wanted to make a timely decision to ensure the health and well-being of all community members who are part of our events," the statement reads.
"With this in mind, we have made the decision to postpone this year's festival. Cork LGBT+ Pride 2020 will not run from September 19 to 28. Please note, this is subject to change based on HSE guidelines.
"The good news is that this means there is more time to create even bigger and better events for the community."
An estimated 15,000 people attended Cork Pride Parade in 2019.
