The New Moon Rising World Tour, also referred to as the Cosmic Egg Tour, was a concert tour by Australian rock band Wolfmother. The tour began on 17 September 2009 with a seven-show leg in Australia, followed by a short European tour in October, a North American leg comprising 24 shows and initially called for a second European leg in 2010. This was followed by an eleven show run in Australia, supporting AC/DC. The band then returned to North America, playing Lollapalooza and various other venues, including two shows in Mexico, and toured Asia and Australia in fall 2010. In early 2011, the band played the Big Day Out festivals in Australia and New Zealand. The tour then culminated after a round of festival and headlining dates in Europe over the summer, and went the studio to commence work on a third studio album. The tour was in support of the band's second album Cosmic Egg, and was the first to be completed by the four-piece lineup of the band formed in January 2009 after the original trio's breakup in August 2008.
On 30 May 2010, the band cancelled their entire tour of Europe, which would have had dates from May through July. The leg was cancelled due to illness. The band was due to play at many festivals, including Rock Am Ring, Rock Im Park, and Download Festival.
