The River Arrow ({{langx|cy|Afon Arwy}}) is a river in the Welsh Marches, rising in Powys in Wales, then flowing into the English county of Herefordshire.{{cite web |title=River Arrow, Pembridge, Herefordshire An Advisory Visit by the Wild Trout Trust March 2015 |url=https://www.wildtrout.org/assets/reports/River%20Arrow%20at%20Pembridge%20Advisory%20Visit%202015.pdf |publisher=The WIld Trout Trust |access-date=7 February 2024}}

It rises near Gwaunceste Hill, then flows south-east through Newchuch and Michaelchurch-on-Arrow. It forms a short section of the England/Wales boundary, before flowing into Herefordshire, and through the town of Kington. It proceeds east through Herefordshire, passing Lyonshall, Staunton-on-Arrow, Pembridge, Eardisland, Arrow Green, Monkland, Ivington, Broadward, and has its confluence with the River Lugg south of Leominster, at Stoke Prior.

Its tributaries include the Gilwern Brook. Others are the Honey Lake Brook, which passes through Ivington Green and Back Brook which joins the Arrow at The Meetings in Kington.

The {{cvt|56|km|adj=on}} Arrow Valley Trail is a long-distance footpath following the river from its source to Leominster.{{cite web |last1= |first1= |title=Arrow Valley Trail |url=https://ldwa.org.uk/ldp/members/show_path.php?path_name=Arrow+Valley+Trail |website=www.ldwa.org.uk |publisher=Long Distance Walkers Association |access-date=7 February 2024}}
