Users can search the map by street, venue or postcode for 5,000 listings of cinema showings, music gigs, theatre shows, club nights and art events for any specific day.
The map also features more than 500 critics' reviews of bars and restaurants.
Stefano Hatfield, editor of thelondonpaper, said: "The mapping tool will allow readers to find our content in a different way.
"Too often a website's content is hidden behind search engines but thelondonknowledge brings all that upfront and instantly shows you where it is.
Thelondonpaper aims to make the online map available on mobile platforms "in the near future", Hatfield said.
