The Hydra World Tour was a concert tour by Dutch symphonic metal band Within Temptation in support of their sixth studio album, Hydra, released by Nuclear Blast on 31 January 2014. To date, it was their eight major tour and their third to see them playing worldwide. The tour passed over four continents and was divided into several legs according to the local of playing, presenting minor setlist variations from concerts of the same leg and a few more variations from leg to leg. A special leg was entitled "Theatres on Fire", in which saw the band playing seated shows at theatres in the Netherlands and Luxembourg.
The tour was commercially successful and the band managed to play in even bigger spaces, an improvement already seen on their previous world tour, as well presenting their first concert at the Wembley Arena and selling out theatre tickets for their theatre seated concerts in the Netherlands. The band also managed to play at several big festivals, like Download Festival, Bloodstock Open Air, and Wacken Open Air. A live album with footage from the Amsterdam concert was released later in 2014, under the name of Let Us Burn – Elements & Hydra Live in Concert.
