Cynthia Noland Dunbar (born June 1964) is an American lawyer and author in Richmond, Texas who served as a Republican on the Texas State Board of Education from 2007 to 2001. The Board establishes policy for the Texas public school system. In 1990, she graduated from Regent University School of Law. During the 2009-2010 academic year, she commuted from her home in Texas to teach in the Liberty University school of law.
In 2006, Dunbar won the Republican nomination for the Texas State Board of Education for District 10. She stated that voters responded to her because she supports teaching intelligent design in science classes. In the general election that year, she defeated Libertarian Martin Thomen, a clerk, with 225,839 votes (70.38%) to 95,034 votes (29.62%). She did not run for reelection in 2010 and her term ended in January 2011.
In her 2008 book One Nation Under God, she asserts that the role of the Christian religion in the public square should be increased. She has been criticized for a section of the book that calls public education a "subtly deceptive tool of perversion," and for stating that "The establishment of public schools is unconstitutional and even 'tyrannical'."
In early 2008, Dunbar ran for the Republican nomination for the United States House of Representatives to represent Texas's 22nd congressional district, the district formerly represented by Tom DeLay. She eventually withdrew and endorsed Shelley Sekula-Gibbs.
In late 2008, Dunbar wrote an article on the Christian Worldview Network website saying that a terrorist attack on America during the first six months of an Obama administration would more likely "be a planned effort by those with whom Obama truly sympathizes to take down the America that is threat to tyranny." Though Dunbar was criticized, she refused to retract the claim saying "I don't have anything in there that would be retractable."
Modifications to Texas K-12 Social Studies Curriculum
As a sitting member of the Texas State Board of Education, in March 2010, Dunbar proposed and won ratification of a number of modifications to Texas K-12 social studies curriculum, notably the removal of mention of Thomas Jefferson and removal of mention of the Age of Enlightenment (in which reason was advocated as the primary source and legitimacy for authority).
- “explain the impact of Enlightenment ideas from John Locke, Thomas Hobbes, Voltaire, Charles de Montesquieu, Jean Jacques Rousseau, and Thomas Jefferson on political revolutions from 1750 to the present.” was changed to
- “explain the impact of the writings of John Locke, Thomas Hobbes, Voltaire, Charles de Montesquieu, Jean Jacques Rousseau, Thomas Aquinas, John Calvin and Sir William Blackstone on political revolutions from 1750 to the present.” 
- ...sidelining Thomas Jefferson, while introducing a new focus on the "significant contributions" of pro-slavery Confederate leaders during the civil war.
- Study of Sir Isaac Newton is dropped in favour of examining scientific advances through military technology.
- a suggestion that the anti-communist witch-hunt by Senator Joseph McCarthy in the 1950s may have been justified.
- One curriculum amendment describes the civil rights movement as creating "unrealistic expectations of equal outcomes" among minorities.
- ...drop[ping] references to the slave trade in favour of calling it the more innocuous "Atlantic triangular trade"
Dunbar says these are important steps to overturning what she believes is the myth of a separation between church and state in the United States. In 2008, Dunbar published a book, One Nation Under God, in which she argued that the United States was ultimately governed by the scriptures.
Textbook controversy: "Mexican-American Heritage"
Dunbar is the CEO of the educational curriculum supplier Momentum Instruction which is publishing the textbook "Mexican-American Heritage". As of September 8, 2016 this textbook was under consideration by the Texas State Board of Education for inclusion in its list of recommended titles.  
- "A foundational premise prescribing that nature encompasses certain laws, obligations, and reasoning that align with Biblical laws and rules by which humans should maintain a certain respect and reverence, first referenced by Lord Bolingbrook [sic] and then his former student Thomas Jefferson." Page 136
- “Chicanos, on the other hand, adopted a revolutionary narrative that opposed Western civilization and wanted to destroy this society.” Page 415
- “Due to the fact that illegal immigrants fear deportation and involvement with legal authorities, crime and exploitation can circulate unabated in their neighborhoods. Those who have hostile views towards American government and culture may also gain strongholds in immigrant communities because of the difficult challenges they face. This may express itself in various unhealthy ways.” Page 454
The textbook has been criticized as containing many inaccuracies.
Media outlets have been quick to condemn the book including CNN in an opinion piece titled "Texas' Mexican heritage textbook a racist travesty".
