Hello evangelinegray-ga,

Thank-you for your question.

With average eyesight and clear dark skies, the most distant object
you can see is the Andromeda Galaxy (also known as M31, Messier 31 or
NGC 224).  It is approximately 2.5 million light years from our
planet.

"The most famous of all galaxies is also the most distant object
visible to the naked eye, and the nearest major galaxy to our Milky
Way.
Distance: c.2,300,000 light years"

"M31, The Andromeda Galaxy
Probably the most distant object you will ever see with your naked eye."
http://www.greenwich-observatory.co.uk/andromeda.html

"Located around 2.5 million light years away, the Andromeda Galaxy is
the most distant object visible to the naked eye, and is considered to
be the sister galaxy of our own Milky Way."

"The Andromeda Galaxy is a spiral galaxy some two million light years
away, making it the most distant object seen with the naked eye."
http://www.dibonsmith.com/m31.htm

"The Andromeda Galaxy is probably the most distant object that can be
seen with the naked eye. Its a sobering thought to say we can see
objects nearly 3 million light years away without optical aids!"
http://www.r-clarke.org.uk/messier/m31.htm

"The nearest large galaxy to our own, a class Sb spiral, and a major
member of the Local Group. Also known as M31 and NGC 224, it lies in
the constellation Andromeda and is the most remote object normally
visible to the naked eye."
