He tweeted the news of the bash this afternoon: "The Party Party - #TPP IT'S GOING TO BE EPIC! You are all invited".
Dotcom will host the party along with some "very, very special guests".
Attendees who wear white to the party will also receive a free copy of his new album.
News of Dotcom's bash comes as the German drops hints about a potential run at politics.
On Sunday he tweeted to his 340,000 followers: "My political party will activate non-voters, the youth, the Internet electorate. We are going to make politics exciting. More on January 20".
Dotcom can't stand for Parliament as he is not a New Zealand citizen, but he can play a central role, with his millions meaning any party he created wouldn't be short on funds.
Tickets to party are available here.
