It then turns southeast, passing through northern [[Croatia]] and, after merging with its main tributary the [[Mur (river)|Mur]], forms most of the border between Croatia and [[Hungary]], before it joins the Danube near [[Osijek]], in Croatia.
==Name==
In ancient times the river was known as ''Dravus'' or ''Draus'' in [[Latin]], and in [[Greek language|Greek]] as Δράος<ref>{{cite journal |last1=Roesler |first1=R. |title=Einiges über das Thrakische |journal=Zeitschrift für die österreichischen Gymnasien |date=1873 |volume=24 |page=111 |publisher=Carl Gerold's Sohn |location=Vienna}}</ref><ref>{{cite journal |last1=Melich |first1=J. |title=Über slavische Flußnamen fremden Ursprungs.

Medieval attestations of the name include ''Dravis'' ({{circa}} AD 670), ''Drauva'' (in 799), ''Drauus'' (in 811), ''Trauum'' (in 1091), and ''Trah'' (in 1136). The name is pre-Roman and pre-Celtic, but probably of Indo-European origin, from the root ''*dreu̯-'' 'flow'.<ref>{{cite book |last1=Snoj |first1=Marko |title=Etimološki slovar slovenskih zemljepisnih imen |date=2009 |publisher=Modrijan |location=Ljubljana |page=124}}</ref> The river gives its name to the [[dravite]] species of [[tourmaline]].<ref>{{cite book |last1=Deer |first1=William Alexander |last2=Howie |first2=Robert Andrew |last3=Zussman |first3=Jack |title=Rock-Forming Minerals: Volume 1B, Disilicates and Ring Silicates |date=1997 |publisher=The Geological Society |location=London |page=559}}</ref>
=== Carpis ===
The Carpis (Greek: Κάρπίς) was a river which, according to Herodotus,<ref>Hdt. 4.49.</ref> flowed from the upper country of the Ombricans northward into the Ister (Danube), whence it has been supposed that this river is the same as the Dravus.<ref>Smith, William, ed. (1854). [http://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0064%3Aentry%3Dcarpis-geo02 "Carpis. 1"]. ''Dictionary of Greek and Roman Geography''. London: John Murray.</ref>
==Geography==
The Drava (along with one of its tributaries, the [[Slizza]]) and the [[Spöl]] are the only two rivers originating in Italy that belong to the Danube [[drainage basin]]. Its main [[Left tributary|left tributaries]] (from the north) are the [[Isel (river)|Isel]] (contributes 39 m<sup>3</sup>/s), the [[Möll]] (25 m<sup>3</sup>/s), the {{illm|Lieser (Drava)|lt=Lieser|de|Lieser (Drau)}} (22 m<sup>3</sup>/s), the [[Gurk (river)|Gurk]] (30 m<sup>3</sup>/s) and the [[Lavant (river)|Lavant]] (12 m<sup>3</sup>/s) in Austria, and the [[Mur (river)|Mur]] (166 m<sup>3</sup>/s) near [[Legrad]] at the Croatian–Hungarian border. Its main right  tributaries (from the south) are the [[Gail (river)|Gail]] (45 m<sup>3</sup>/s) in Austria, the [[Meža]] (12 m<sup>3</sup>/s) and [[Dravinja]] (11 m<sup>3</sup>/s) in Slovenia, and the [[Bednja (river)|Bednja]] (? m<sup>3</sup>/s) in Croatia.

==Course==
[[File:Drauquellen.jpg|thumb|left|Drava sources, Innichen]]
The sources of the Drava are located at the [[drainage divide]] between the market town of Innichen/San Candido and neighbouring [[Toblach]]/[[Dobbiaco]] in the west, where the [[Rienz]] River rises, a tributary of the [[Adige]]/[[Etsch]]. At Innichen itself the 16+ km {{illm|Sextner Bach|de|}},<ref>[http://umwelt.provinz.bz.it/wasser/suedtiroler-fluesse-und-baeche.asp?news_action=4&news_article_id=550401 Sextner Bach] at the South Tyrol/Alto Adige agency for the environment website</ref> originating near the [[Sextener Rotwand]], joins the ~2&nbsp;km long source creek. The river than flows eastwards and after 8 kilometres crosses into East Tyrol in Austria. At [[Lienz]] it flows into the [[Isel (river)|Isel]], sourced from the glaciers of the [[Venediger Group|Venediger]] and [[Glockner Group]]s. The Isel (average discharge 39&nbsp;m³/s) is almost three times larger than the Drava (14&nbsp;m³/s) where they meet and, starting from the source of its tributary {{illm|Schwarzach (Isel)|lt= Schwarzach|de|}} under the [[Rötspitze]], the Isel (ca. 64&nbsp;km) is also longer than the combined Drava and Sextner Bach (ca. 60&nbsp;km) to that point.<ref>Hydrographisches Jahrbuch Österreichs 2008, S. OG322</ref><ref name=jdrcar/>
The river then flows east into Carinthia at [[Oberdrauburg]]. The river separates the [[Kreuzeck group|Kreuzeck]] range of the [[High Tauern]] in the north and the [[Gailtal Alps]] in the south, passes the [[Sachsenburg]] narrows and the site of the ancient city of [[Teurnia]], before it reaches the town of [[Spittal an der Drau]]. Downstream of [[Villach]], it runs along the northern slopes of the [[Karawanks]] to [[Ferlach]] and [[Lavamünd]].
The Drava passes into Slovenia at [[Gorče]] near [[Dravograd]], from where it runs for {{convert|142|km|mi}}{{GeoQuelle|SI|SURS}} via [[Vuzenica]], [[Muta, Slovenia|Muta]], [[Ruse, Slovenia|Ruše]], and [[Maribor]] to [[Ptuj]] and the border with Croatia at [[Ormož]]. The river then passes [[Varaždin]], [[Belišće]] and [[Osijek]] in Croatia, and [[Barcs]] in Hungary. It is navigable for about {{convert|90|km|mi}} from [[Čađavica, Croatia|Čađavica]] in Croatia to its mouth.
The [[hydrological]] parameters of Drava are regularly monitored in Croatia at [[Botovo, Croatia|Botovo]], [[Terezino Polje]], [[Donji Miholjac]] and Osijek.<ref>{{cite web | url = http://hidro.hr/hidro_e.php?id=hidro&param=Podaci_e | title = Daily hydrological report | publisher = [[State Hydrometeorological Bureau of the Republic of Croatia]] | access-date = 2010-09-09 | archive-date = 2010-05-30 | archive-url = https://web.archive.org/web/20100530062812/http://hidro.hr/hidro_e.php?id=hidro&param=Podaci_e | url-status = dead }}</ref>
