The vast majority of those campaign contributions - about 93 percent - came from individual donors. Less than 2 percent came from political action committees.
According to reports filed with the Federal Election Commission, the Massachusetts Democrat also spent nearly $1.6 million on operating expenses during the same two-year period.
Warren had more than $1.6 million left in her campaign account at the end of 2014.
During her 2012 campaign to oust then-incumbent Republican U.S. Sen. Scott Brown, the former Harvard Law School professor raised more than $42 million.
The race was easily the most expensive political contest in Massachusetts history.
