The 'What I've Done' hitmakers scooped the Alternative Artist accolade at the ceremony at the Microsoft Theater in Los Angeles on Sunday night (19.11.17), and paid tribute to the singer, who took his own life in July 2017 aged 41.
Linkin Park singer Mike Shinoda told the crowd: ''We want to dedicate this award to him, to his memory, to his talent, to his sense of humour, to his joy.
''And remember, you guys, all of you tonight, whether you're a fan or an artist - I want you guys to take a moment to appreciate what you've got. And make Chester proud.''
The US rockers also took to their Twitter account to thank their fans for voting for them in the category, in which they beat off competition from Imagine Dragons and Twenty One Pilots.
They wrote: ''Thank you to our fans for all of your support and for voting for us at this year's @AMAs. We took home Favorite Artist - Alternative Rock #AMAs
''Thank you to all the fans who voted. We love you so much. Take a moment to appreciate the people you love and #MakeChesterProud #AMAs (sic)''
Last week, Linkin Park - who are also made up of Rob Bourdon, Brad Delson, Dave Farrell and Joe Hahn - dedicated their upcoming live album, 'One More Light Live', to the late frontman.
They said in a statement: ''We dedicate this live album to our brother Chester who poured his heart and soul into 'One More Light.'
''After we finished recording the album, we joked with Chester that - since he had delivered so many stunning performances in the studio - he had set the bar extra high to produce that alchemy on stage each night.
''Not surprisingly, he welcomed the challenge.''
