There are different definitions. For FAA certification purposes, a heavy aircraft is anything over 47,000# (or something like that)...so 50 seat RJ's qualify.
For ATC wake seperation, heavy is about what slice said (I thought it was over 255,000# but slice should know).

Not so. This is off the FAA website:
Weight class is coded into three ordered levels: Small aircraft are those of
41,000 lbs. or less maximum certificated takeoff weight;
Large aircraft are those of more than 41,000 lbs. up to
255,000 lbs. maximum certifi cated takeoff weight; Heavy
aircraft are those capable of takeoff weights of more than
255,000 lbs. whether or not they are operating at this
weight during a particular phase of flight

300,000 lbs USED to be the FAA's defintion of a heavy jet. Whether it was operating at that weight or not. Then when the wake turbulence research was comlpeted after some accidents involving the 757, it was lowered to the mid 250's.
RJ's are considered "large" aircraft.

by gosh... your right! I read 255,000 in my old employers FOM, but the AIM reference no longer gives a weight... I knew ICAO was 136,000 kilograms, but your response had me back into google... gotta love it.
as to the other poster, although different employers come up with different numbers on the applicaiton for heavy... if it doesn't specify, I think below is what I would go with...
FAA Order 7110.65, Air Traffic Control
AIRCRAFT WEIGHT CLASSES
a. Heavy. Aircraft capable of takeoff weights of more than 255,000 pounds whether or not they are operating at this weight during a particular phase of flight.
b. Large. Aircraft of more than 41,000 pounds, maximum certificated takeoff weight, up to 255,000 pounds.
c. Small. Aircraft of 41,000 pounds or less maximum certificated takeoff weight.
