	~~In [[mathematics]], particularly [[abstract algebra]], an '''algebraic closure''' of a [[field (mathematics)\|field]] ''K''~~ is ~~an [[algebraic extension]] of~~ ''~~K'' that is [[algebraically closed field\|algebraically closed]]~~. It is ~~one of many [[closure (mathematics)\|closures]]~~ in ~~mathematics~~.

	~~Using [[Zorn~~'s ~~lemma]], it can~~ be ~~shown that every field has an algebraic closure~~,<~~ref~~>M. F. ~~Atiyah and I~~. G. ~~Macdonald (1969)~~. ~~''Introduction to commutative algebra''. Addison~~-~~Wesley publishing Company~~. ~~pp. 11~~-12.<~~/ref~~> ~~and that the algebraic closure of a field ''K''~~ is ~~unique [[up to]] an [[isomorphism]] that [[fixed point (mathematics)\|fixes]] every member of ''K''. Because of this essential uniqueness, we often speak of ''~~the'~~' algebraic closure of ''K''~~, ~~rather than ''an'' algebraic closure of ''K''~~.

	~~The algebraic closure of a field ''K'' can be thought of as the largest algebraic extension of ''K''~~.
	~~To see this~~, ~~note that if ''L'' is any algebraic extension of ''K'', then~~ the ~~algebraic closure of ''L'' is also an algebraic closure of ''K''~~, and ~~so ''L'' is contained within~~ the ~~algebraic closure of ''K''~~.
	~~The algebraic closure of ''K''~~ is ~~also the smallest algebraically closed field containing ''K''~~,
	~~because if ''M'' is any algebraically closed field containing ''K~~''~~, then the elements~~ of ~~''M'' which are [[algebraic extension\|algebraic over]] ''K'' form~~ an ~~algebraic closure of ''K''~~.

	~~The algebraic closure of~~ a ~~field ''K'' has the same [[cardinal number\|cardinality]] as ''K'' if ''K''~~ is ~~infinite, and is [[countably infinite]] if ''K'' is finite.~~

	~~==Examples==~~
	*The [[fundamental theorem of algebra]] states that the ~~algebraic closure~~ of ~~the field~~ of ~~[[real number]]s is~~ the ~~field of [[complex number]]s~~.

	*The algebraic closure of the ~~field~~ of ~~[[rational number]]s is the field of [[algebraic number]]s.~~

	*There are many countable algebraically closed fields within the complex numbers, ~~and strictly containing the field of algebraic numbers; these are the algebraic closures of transcendental extensions of~~ the ~~rational numbers~~, e.~~g. the algebraic closure of '''Q'''(π).~~

	*For a [[finite field]] of [[prime number\|prime]] order ''p'', the algebraic closure is ~~a [[countably infinite]] field which contains a copy of the field of order ''p''~~<~~sup~~>~~''n''~~<~~/sup~~> ~~for each positive [[integer]]~~ '~~'n'' (and is in fact~~ the ~~union of~~ these ~~copies)~~.~~<ref>{{citation\|title=Infinite Algebraic Extensions~~ of ~~Finite Fields\|volume=95\|series=Contemporary Mathematics\|first1=Joel V~~.~~\|last1=Brawley\|first2=George E.\|last2=Schnibben\|publisher=American Mathematical Society\|year=1989\|isbn=9780821854280\|contribution=2.2~~ The ~~Algebraic Closure of a FInite Field\|pages=22–23\|url=http://books~~.~~google.com/books?id=0HNfpAsMXhUC&pg=PA22}}.</ref>~~

	~~==Separable closure==~~
	~~An algebraic closure ''K<sup>alg</sup>''~~ of ~~''K'' contains~~ a ~~unique [[separable extension]] ''K<sup>sep</sup>''~~ of ~~''K'' containing all (algebraic) [[separable extension]]s of ''K'' within ''K~~<~~sup~~>~~alg~~<~~/sup~~>''. ~~This subextension is called a~~ '~~''separable closure''' of ''K''.
