Lowton completes switch to Villa from Sheffield United
The 23-year-old Lowton has signed a four-year deal which will take him up to the end of the 2015-16 season at Villa.
He is the club's third signing of the transfer window, following the acquisition of Karim El Ahmadi and Brett Holman.
Villa boss Paul Lambert described Lowton as "a bright prospect with the potential to be a really good player for us."
Chesterfield-born Lowton is predominantly a right-back but has displayed his versatility in the past by operating in a number of roles across the back four and in midfield for the Blades.
He was an ever-present for Danny Wilson's team in 2011-12, playing in 52 matches in all competitions.
Lowton made 47 appearances in League One - including the playoffs - as United narrowly missed out on promotion with a penalty shootout defeat to Huddersfield in the play-off final.
He found the net six times during the league campaign.
"It's every boy's childhood dream to play in the Premier League and it was one of mine," Lowton said.
"This opportunity is fantastic and I thank the manager for giving it to me. Hopefully I can repay the faith that's he's shown in me and keep going at a higher level.
"Just from driving up to the training ground you can see the difference in the quality of things. The training ground looks spectacular and the pitches look phenomenal. It's a massive club in the Premier League with a big fan base and I'm looking forward to getting to work as soon as I can.
"I played the majority of last season at right back but I have played right midfield and central midfield as well. I think my main asset is going forward and my technical ability but obviously I'm going to try and add whatever the manager is after from me. These are exciting times for me and I can't wait to go out and start playing."
Lambert said: "Matthew is a really talented young player who brings a lot of things that can really benefit the club. He's a good player already and he's only young so he has the potential to be a really good player for us.
"He's hungry to succeed and to go further in the game, both of which are attributes that we want at this football club and that we are looking for.
"We won't put any pressure on him, we just want him to go out and enjoy playing. What he's done so far at Sheffield United has been great so hopefully we can progress him a bit and he'll do very well for us."
Lowton also spoke of his excitement at working with Lambert and with his new team-mates.
"It's fantastic to think I'll be playing under Paul Lambert. I was flattered when I heard the interest and, when speaking to him, he's helped me settle in nicely so far. Hopefully we can get on well and I can fight for my place and play a few games this season.
"As a League One player last season, Premier League players are what everyone looks up to. Seeing guys like Darren Bent and Gabby Agbonlahor and people like that is fantastic. Meeting players who have played international and Premier League football all their lives is amazing.
"You can sense the buzz around the place at the moment. The lads were all having a laugh and joke when I came in this morning and they've all been very welcoming which was very good of them. It's a new era with the new manager and a few new signings.
"The squad has already got some fantastic players, everybody knows them so hopefully we can all come together and have a successful season."
A product of Sheffield United's academy, Lowton progressed through the youth ranks before making his first team debut as a substitute against Cardiff in March 2010.
He had already gained experience of senior football during loan spells at non-league Sheffield FC and United's Hungarian partner side, Ferencvaros.
Lowton contributed to Ferencvaros winning promotion during the 2009-10 campaign before returning to Bramall Lane.
The following season, he featured 32 times for United and chipped in with four goals.
