The US economy grew by just 0.2% in the first three months of the year, compared with the same period in 2014, according to the US Commerce Department.
The figure was well below analysts' expectations of 1% growth. It also falls from 2.2% in the previous quarter.
A second tough winter in a row and the continued battle for energy companies against falling oil prices are believed to be the two main reasons for slow growth.
The government said there were signs that growth would pick up in the second quarter.
