The campaign's announcement Thursday came two days after Obama lost three out of four primaries to Clinton. Clinton's victories stopped his winning streak and extended the race into an unpredictable future.
Obama's February total was his second fundraising record. He raised $36 million in January, more than any other presidential candidate who has ever been in a contested primary.
More than $54 million of the February money was for the primary election. His combined January and February totals nearly matched was he raised last year. The campaign said it raised $45 million through the Internet in February and had 385,000 new contributors for a total of more than 1 million donors.
Riding her victory wave, Clinton's camp announced Thursday that she raised $4 million online since Tuesday's presidential primary successes in Ohio, Texas and Rhode Island.
The Clinton campaign said it had raised the money from the time polls closed Tuesday through noon Thursday. It reported 30,000 new donors. The influx of money made their online total raised for this month $6 million, the campaign announced.
Clinton raised an impressive $35 million in February, a significant recovery from January when Obama raised more than twice her total. But Obama has outpaced her both in fundraising and spending during the nominating contests.
"We're going to have the funds we need to keep this campaign going, to keep Hillary Clinton's message out there," senior adviser Ann Lewis said in a teleconference with reporters.
Past victories have also caused upticks in giving. The Clinton campaign, for instance, raised more than $1 million in the 24 hours following her New Hampshire victory on Jan. 8. Obama raised $1.2 million the day after winning the Iowa caucuses and he raised even more in the 24 hours after losing in New Hampshire.
Clinton had to lend her campaign $5 million at the end of January, but has seen her finances improve since then. She reported raising $34 million for the primary in February.
Obama and his allies outspent her in Texas and Ohio in advertising.
