Baker, 18, had put his five-ticket allocation up for auction on the social networking site against club rules.
In the dock: England U19 defender Nathan Baker has been rapped for putting his Carling Cup final tickets up for auction on Facebook
Currently on loan at Lincoln City, Baker, an England Under 19 international, has been branded 'foolish' by Villa and has been told he cannot attend the final against Manchester United at Wembley on February 28.
A Villa spokesman said: 'The club is saddened that Nathan has been so foolish. All of the players were made aware that tickets for the Carling Cup final are available for their own use only and the message has been repeated.
'It shouldn't be forgotten, however, that Nathan is just 18 and he has a lot to learn. His actions were naive and he is extremely embarrassed and regretful at having let down himself, the club and Aston Villa fans.'
Baker said: 'I appreciate it is a privilege to be part of Aston Villa FC and one day I hope to play in the first team, but I understand my behaviour off the pitch must speak as loudly as my actions on the pitch.
While I will be sorry not to be able to cheer Villa on at Wembley, I appreciate it would be inappropriate for me to have these tickets given my actions.'
