Tony Blair is to teach students at Yale University in the US when he leads a seminar on faith and globalisation.
Tony Blair will take part in a number of events around the Yale campus
The former prime minister has been appointed as a fellow at Yale and will begin teaching next year.
The prestigious Connecticut university said the work was related to Mr Blair's Faith Foundation which will be launched later this year.
Mr Blair's other appointments have included as a Middle East envoy and an adviser to investment bank JP Morgan.
Mr Blair has also left the Anglican Church to become a Roman Catholic since leaving office.
A statement said: "Yale University is pleased to announce the appointment of [former] Prime Minister Tony Blair as the Howland Distinguished Fellow for the next academic year.
"Mr Blair will lead a seminar at Yale and participate in a number of events around the campus."
Details of the course are being discussed with Yale's School of Management and Divinity.
Yale president Richard C Levin said Mr Blair's appointment was a "tremendous opportunity" for the university.
He said: "As the world continues to become increasingly inter-dependent, it is essential that we explore how religious values can be channelled toward reconciliation rather than polarisation.
"Mr Blair has demonstrated outstanding leadership in these areas and is especially qualified to bring his perspective to bear."
