A national secondary road ({{lang-ga|Bóthar Náisiúnta den Dara Grád}}) is a category of road in Ireland. These roads form an important part of the national route network, but are secondary to the main arterial routes which are classified as national primary roads. National secondary roads are designated with route numbers higher than those used for primary roads, but with the same "N" prefix. Routes N51 and higher are all national secondary roads.

National secondary roads have a default speed limit of 100 km/h (62.5 mph), as along with national primary routes, they fall into the speed limit category of national roads.

There are 2657 km of national secondary roads in Ireland, making up slightly over 50% of the entire national route (national primary and national secondary) network.^[1] National secondary routes are generally more poorly maintained than primary routes (although their quality can vary widely), but often carry more traffic than regional roads. Almost the entire network of national secondary roads is single carriageway, although there are some short sections of dual carriageway on the Tallaght bypass section of the N81, on the N52 at Dundalk, on the N85 at Ennis, on

the N67 at Galway, on

the N62 at Athlone, on the N69 at Tralee and on the N71 between Cork and Bandon. Typically, national secondary roads are of a similar standard or higher than regional roads although some are of lower quality than the better sections of regional roads. Many of them have been resurfaced with higher quality pavements in recent years with relatively smooth surfaces and good road markings and signposting. However, road widths and alignments are often inadequate, with many narrow and winding sections.

In the past, most national secondary roads would have run through the centres of the towns on their routes; however, that is becoming less and less often the case. For example:

• The N52 bypasses Nenagh, Mullingar, and the centre of Dundalk (as a relief road), as well as forming the now complete N52 bypass of Tullamore.
• The N55 (together with the N3) bypasses Cavan.
• The N56 forms part of the Donegal bypass.
• The N61 and the N63 bypass Roscommon.
• The N69 forms part of the Tralee bypass.
• The N71 bypasses Halfway and Skibbereen.
• The N74 bypasses Cashel.
• The N76 bypasses Callan.
• The N77 forms the northern part of the Kilkenny ring road.
• The N80 bypasses Carlow.
• The N85 bypasses Ennis.

The former N8 bypass of Mitchelstown was re-classified as the N73 when the Fermoy (Moorepark) to Kilbehenny section of the M8 was completed.

Most national secondary roads were originally Trunk Roads under the old system of road classification in Ireland, although some sections of national secondary routes were formerly Link Roads. A large number of less important Trunk Roads became regional roads when the road classification system changed from 1977 onward, including some roads, such as the N72 between Killarney and Killorglin, the N86 and the N87, which were originally re-classified as regional roads but later re-classified again as national secondary routes. In 1994, three national secondary roads were reclassified as national primary roads: the N57 between Swinford and Ballina became the N26, the N64 between Oranmore and Claregalway became part of the N18 and the N79 between New Ross and Enniscorthy became the N30. In addition, a section of the N60 between Castlebar and Westport became part of the N5.

Some national secondary roads, though not arterial routes between major cities, connect scenic areas to major population centres. For example, the N59 through County Galway and County Mayo, the N70 road through County Kerry (see Ring of Kerry) and the N71 through West Cork. For this reason, many national secondary roads are well-traveled by tourists.
