David Walker (February 19, 1806 – September 30, 1879) was an American lawyer, politician, and judge and notable early settler of Fayetteville, Arkansas.

[7] He became active in Whig politics and was elected to a two-year term as prosecuting attorney for the Third Circuit Court of Arkansas Territory beginning September 13, 1833.

Walker resigned from the General Assembly to run for Arkansas's at-large congressional district in the 1844 election as the Whig party candidate.

[10] Having become one of the most wealthy citizens in the region, in addition to his law practice, Walker raised cattle and grew grains and fruit on a 1,000 acres (400 ha) farm on the West Fork of the White River with twenty-three slaves.

[14] After Confederate guns fired on Fort Sumter and President Lincoln issued a call for support from the states, many advocated for recalling the convention, but others were opposed.

[17] Walker had requested a re-vote to produce a unanimous decision to present a unified front, but Isaac Murphy remained opposed.

[11] After closing the Convention with Arkansas's secession decided and entry into the Confederate States of America underway, Walker returned to his home and resumed farming.

Over time, Union troops and roving marauders ravaged his property and radicalized the former Whig into a supporter of the Confederate States of America.
