42 pioneering projects across the country will benefit from their share of the funding, as part of the government's drive to improve care for people with autism.
The schemes will test new ways of supporting people with autism including crisis prevention work and employment help. The projects will then be evaluated next summer.
Liberal Democrat Care Minister Norman Lamb said: "I am delighted that we have been able to contribute funding for the excellent work that these projects carry out.
"We want to ensure that young people and adults with autism have the right support and opportunities to lead fulfilling and rewarding lives."
In addition, all local authorities are now able to apply for funding to make community areas more autism-friendly. The £18,500 grant could be used for electronic equipment such as iPads to improve services for people with autism, or used to refurbish quiet rooms.
Local authorities have until December 12 to set out their plans on how to spend the funds.
