Yes. With the Emancipation Proclamation and 13th Amendment, he abolished slavery (though only in the south in the beginning.) Lincoln was deceased and did not sign the 13th Amendment to the US Constitution, which finally freed Slaves in the Union North and the Confederate South.
Abraham Lincoln was president when the 13th amendment was introduced, but Andrew Johnson was president in 1866 (he was sworn in following Lincoln's death in April of 1865). The amendment was actually ratified on December 6, 1865.
Abe Lincoln signed the Emancipation Proclamation in 1863, but that freed the slaves of the South. Slavery was officially abolished thanks to the 13th Amendment to the Constitution, approved in December 1865.
