Matthew Jason Bloom, better known as Albert or A-Train (born on November 14, 1972 in Peabody, Massachusetts) is a professional wrestler currently performing for World Wrestling Entertainment on the Smackdown brand.

Bloom portrayed several characters throughout his career since making his debut in 1997. This included a few runs in Power Pro Wrestling in Memphis as Baldo and in the then-WWF as the bizarre Prince Albert. In 2000, he was repackaged as \'Albert', the wrestler formerly known as Prince.

The Albert character was in a tag team with Test. T & A (Test and Albert) fell under the tutelage of the vivacious Trish Stratus. His career highlights include being a one-time WWF Intercontinental Champion. Before Backlash 2001 in Chicago, Illinois, Bloom joined forces with X-Pac and Justin Credible, forming the team X-Factor.

In late 2002, Bloom was given a new ring name: A-Train.
