The State Department says Clinton will meet Wednesday with Senegal's new president, Macky Sall, and highlight the country as an example of the resilience of democratic institutions.
Sall defeated former President Abdoulaye Wade in a March election after controversy over whether Wade was entitled to run for a third term.
Clinton will also visit South Sudan, Africa's newest nation following its break with Sudan last year. Her visit coincides with a U.N. Security Council debate over possible measures to end ongoing oil, border and citizenship disputes between the two countries.
Clinton is expected to highlight U.S. programs on HIV/AIDS, education and development during her tour, which includes stops in several other countries, including Uganda, Kenya and South Africa.
The secretary has made several previous trips to sub-Saharan Africa. Last year, she visited Ethiopia, Zimbabwe and Tanzania.
