Trionfale (Italian pronunciation: [tri.oɱˈfaːle]) is the 14th quartiere of Rome (Italy), identified by the initials Q. XIV.

The little church of San Lazzaro in Borgo, where pilgrims had to stop before entering the city walls, bears witness to this.

To the west, Trionfale borders with quartiere Della Vittoria (Q. XV), whose border is delineated by the stretch of Via Trionfale between Via Igea and Viale delle Milizie, as well as with rione Prati (R. XXII), the boundary being marked by Via Leone IV.

Southward, Trionfale shares its border with the Vatican City and with quartiere Aurelio, from which it is separated by Viale Vaticano, Via di Porta Pertusa, Via Aurelia, Via Anastasio II, Via Angelo Emo, Via di Valle Aurelia and Via del Pineto Torlonia.

Odonyms are focused, in the southern part of Trionfale, on prominent admirals, Navy heroes and naval combats; in the north-western area, streets and squares are mostly named after Italian war heroes (next to Viale delle Medaglie d'Oro) and ancient authors.
