The US unemployment rate dipped to 5.9% in September, a six-year low, official figures have shown.
The rate fell from 6.1% in August and is the lowest recorded since July 2008.
US Labor Department also said that employers added 248,000 jobs last month, and the job growth figures for August and July were revised upwards.
The jobs figures are seen as a significant gauge of the health of the economy and there has been much debate over when US interest rates will rise.
The US Federal Reserve has kept interest rates close to zero since the financial crisis in 2008.
US markets cheered the news, with the Dow Jones Industrial Average rising over 100 points.
The US dollar was pushed higher as expectations rose that interest rates would go up sooner than previously predicted.

"The most important item in this report is the drop in the unemployment rate below 6%. (Fed Chair Janet) Yellen has said there is only so much slack if the unemployment rate falls below 6%," said Christopher Low, chief economist at FTN Financial in New York.
The Federal Reserve's stimulus programme, known as "quantitative easing", is due to end this month. Its aim was to keep long-term interest rates low using the purchase of bonds, and thus to boost spending.
The Federal Reserve has indicated it will raise short term interest rates if the economy continues to grow. Janet Yellen has given no firm date for the rise, but the Fed has said the move will come a "considerable time" after the stimulus programme ends.
"This (jobless) number will continue to support the notion that the economy is growing," said Paul Nolte at Kingsview Asset Management in Chicago, "and it isn't so strong that the Fed will raise rates anytime soon".
The Labor Department said 69,000 more jobs were created in July and August than previously estimated. It also said nearly 100,000 jobseekers stopped looking for work in September.
The largest rise in employment was in professional and business services, including management and legal services, which saw an increase of 81,000 jobs in September.
The retail sector added 35,000 jobs compared with the previous month. Employment in the health care, construction and leisure and hospitality sectors also continued to increase.
