Andrew Gary Johns (born 19 May 1974) is an Australian former professional rugby league footballer of the 1990s and 2000s. He is considered by many to be one of the greatest players of all time. Hailed as the best halfback in the world for many years, he captained the Newcastle Knights in the National Rugby League and participated in the team's only two premiership victories in 1997 and 2001, playing a club record 249 games for the Knights. Johns also represented his country at two World Cups, and on one Kangaroo tour, playing in total 21 Test matches for the national side.

On 26 August 2007 Johns was arrested for fare evasion on the London Underground, and subsequently found to be in possession of one ecstasy tablet. He was cautioned and released with no further charges. Johns initially claimed that an unknown person had pushed the tablet into his pocket which he later forgot to remove before leaving the crowded venue. This initial statement was met with a great deal of cynicism from both the press and the public. On 30 August, Johns revealed, live on the Footy Show, that he had regularly taken ecstasy throughout his playing career, mainly during the off-season. He claimed he had suffered from depression and bipolar disorder and the drugs helped him in dealing with the high level of psychological 'pressure' associated with his career as an elite sportsman. Not long after the incident he released his 'tell-all' autobiography that went into further details regarding his depression and drug use while playing in the NRL.  The ARU released a press statement shortly after the controversy arose, stating that Johns' drug use was known to the ARU and was a key factor in its decision to not proceed with contractual negotiations in 2004. Brett Robinson, then high-performance unit manager, said that, as well as Johns' age and injury history, the knowledge of his drug taking had been influential in the ARU making its final decision.  When Johns was named the Best Player of the Last 30 Years in early 2008, the accolade allayed concern that Johns' shock drug admission the year before had tarnished his remarkable efforts on the field for Newcastle, NSW and Australia. On receiving the award he was quoted as saying his health was now in great shape. "I'm at the best place I have been in a long time," he said. "It's not until you step away that I realise all the pressure I was under, I'm not going to miss playing at all."
