More than 18,000 summer jobs and 190,000 activities for young adults between the ages of 16 and 24 are available.
The initiative, dubbed One Summer Chicago, aims to provide "valuable job training and work experience" for youth.
"We want children and young adults to be safe and engaged this summer by taking full advantage of all of the excellent work, educational and recreational opportunities that we have assembled," said Emanuel.
Of the 18,000 job opportunities, 7,000 will be with the After School Matters program, and 3,900 will be with the Chicago Park District. An additional 2,200 jobs will be with the Chicago Housing Authority.
