A '''caffeinated drink''', or '''caffeinated beverage''', is a [[drink]] that contains [[caffeine]], a [[stimulant]] that is legal practically all over the world. Some are naturally caffeinated while others have ''caffeine added'' as an ingredient.

The most common naturally caffeinated beverages are [[coffee]] and [[tea]], which in one form or another (usually served hot, but sometimes iced) feature in most world cultures.<ref name="Teas and Caffeine">{{cite journal|last1=David|first1=Iulia Gabriela|last2=Bizgan|first2=Ana-Maria Cristina|last3=Buleandra|first3=Mihaela|last4=Popa|first4=Dana Elena|last5=Moldovan|first5=Zenovia|last6=Bandea|first6=Irinel Adriana|title=Rapid determination of total polyphenolic content in tea samples based on caffeic acid voltammetric behaviour on a disposable graphite electrode.|journal=Food Chemistry|date=April 2015|volume=173|pages=1059–1065|doi=10.1016/j.foodchem.2014.10.139|pmid=25466125}}<!--|accessdate=February 19, 2014--></ref> Other drinks are artificially caffeinated as part of their production process. These include certain [[soft drink]]s (primarily [[cola]] drinks), and also [[energy drinks]] designed as a stimulant, and to perpetuate activity at times when the user might ordinarily be asleep.

The consumption of caffeinated drinks is often intended entirely or partly for the physical and mental effects of caffeine. Examples include the consumption of tea or coffee with breakfast in many westernized societies, in order to 'wake oneself up', or the deliberate consumption of energy drinks by students wishing to study through the night, or revellers seeking to maintain an alert attitude during social recreation.<ref name="Evolution of Energy Drinks">{{cite journal|last1=Gimba|first1=Casimir Emmanuel|last2=Abechi|first2=Stephen Eyije|last3=Abbas|first3=Nurudeen Sulaiman|title=Evaluation of caffeine, aspartame and sugar contents in energy drinks.|journal=Journal of Chemical and Pharmaceutical Research|date=2014|volume=6|issue=8|page=39-43}}</ref> Caffeine can cause a physical dependence, if consumed in excessive amounts.<ref name="Caffeine Addiction in High Schoolers">{{cite journal|last1=Rockett|first1=Ian R.H.|last2=Putnam|first2=Sandra L.|title=Caffeine "Addiction" in High School Youth: Evidence of an Adverse Health Relationship|journal=Addiction Research and Theory|date=February 2002|volume=10|issue=1|pages=31–42|doi=10.1080/16066350290001696|s2cid=144490604}}<!--|accessdate=February 19, 2014--></ref> The need for caffeine can be identified when individuals feel headaches, fatigue and muscle pain 24 hours after their last energy drink.<ref name="Remedy Health Media">{{cite web|title=Caffeine (and its effects)|url=http://www.healthcentral.com/encyclopedia/408/665.html|website=Health Central|publisher=Remedy Health Media|accessdate=5 November 2014|archive-date=5 November 2014|archive-url=https://web.archive.org/web/20141105064817/http://www.healthcentral.com/encyclopedia/408/665.html|url-status=live}}</ref>

Some commercially distributed drinks contain [[guarana]], a [[South American]] berry with a caffeine content about twice that of coffee beans.<ref>Bempong DK, Houghton PJ, Steadman K (1993).

Many caffeinated drinks also have decaffeinated counterparts, for those who enjoy the taste, but wish to limit their caffeine intake because of its [[caffeine#Physical effects|physical effects]], or due to [[caffeine#Religion|religious]] or [[health effects of caffeine#Negative effects|medical]] perceptions of the drug and its effects.

In recent years, some alcoholic beverage companies have begun to manufacture [[caffeinated alcoholic beverage]]s. The manufacturing of such beverages has been met with much controversy.<ref name="Mixing Alcohol and Caffeine">{{cite journal|last1=Benson|first1=Sarah|last2=Verster|first2=Joris C.|last3=Alford|first3=Chris|last4=Scholey|first4=Andrew|title=Effects of mixing alcohol with caffeinated beverages on subjective intoxication: A systematic review and meta-analysis.|journal=Neuroscience & Biobehavioral Reviews|date=November 2014|volume=47|pages=16–21|doi=10.1016/j.neubiorev.2014.07.008|pmid=25036891|s2cid=42390630}}<!--|accessdate=February 19, 2015--></ref><ref>{{Cite web|url = https://thesupplementswiki.com/ingredients/caffeine-wiki-benefits-uses-side-effects-and-dosage/|title = Caffeine Wiki: Benefits, Uses, Side Effects and Dosage|date = 27 May 2020|access-date = 30 May 2023|archive-date = 21 March 2023|archive-url = https://web.archive.org/web/20230321003847/https://thesupplementswiki.com/ingredients/caffeine-wiki-benefits-uses-side-effects-and-dosage/|url-status = live}}</ref>
