Longitude Festival is a music festival that takes place during July every year in Dublin, Ireland. Since 2013, Marlay Park has been home to the festival.

When the festival first started in its early years the line up was mostly bands and singer songwriters such as Phoenix, Kodaline, and Sam Smith. As the festival evolved in later years it mostly consisted of hip hop artists such as Stormzy, Travis Scott, and Ski Mask the Slump God.

There are multiple bars around the festival owned by Heineken, Bacardi and Red Bull. Around the venue multiple food stalls can be found with a wide variety of food and drink. There is also the Longitude Lounge which is sponsored by Coca-Cola and is accessible by VIP ticket holders.

Three Ireland offer free portable battery banks at the festival for a small deposit that can be redeemed if you give the battery bank back by the end of the festival. The festivals age restrictions require under 16’s to be accompanied by an adult. Longitude Festival has a sister festival in the United Kingdom called Latitude Festival.
