Yes, most nationalities are able to obtain a single-entry visa at the airport or port in Aqaba, valid for 14 days and costing JOD10.

Although entrance visas are obtainable at the airport for visitors arriving by airplane, those arriving by land must get a visa prior to arrival. These are obtainable from any Jordanian diplomatic mission abroad, where they generally take a day to be received. Visas cannot be obtained at Jordan's land border crossings

Please make sure to consult your nearest Jordanian embassy for any visa requirements that you may be subject to.
