This list is limited to text composed by Tolkien in Old English which are at least several lines long, ignoring smaller things like single lines of dialogue, names, and Old English titles Tolkien gives to his non Old English works
Many of these texts do not have titles given by Tolkien, and so I refer to them by the opening words instead.
All together, there is a little over 1,000 published lines of Tolkien's Old English compositions, the vast majority of which (around 70%) are not accompanied by any Modern English translations.
There are likely more that remain unpublished.

Ælfwine's translations In parallel with 1930s Silmarillion texts, Tolkien also tried writing some of them as prose in Old English. These have been published in The Shaping of Middle-earth, all without translation. (Some excerpts with translation and analysis can be found in "Writing for an Anglo-Saxon Audience in the Twentieth Century: J.R.R. Tolkien's Old English Chronicles" by Maria Artamonova)
- Pennas - (translation by Ælfwine of the first four paragraphs of Quenta Noldorinwa) - Shaping, 56 lines
- 'Þéos gesegen wearþ ǽrest...' (translation by Ælfwine of the opening of the Annals of Valinor, until just after the destruction of the two trees) - Exists in two versions, of 55 lines and 158 lines. Christopher says that the second is very close to the Modern English version given in the book. Two other very short texts (27 lines and 10 lines) are also given, further developing the opening lines of the second version.
- Beleriandes Géargesægen (translation by Ælfwine of the opening of the Annals of Beleriand, until just after the Dagor Aglareb) - 88 lines
The Lost Road / The Notion Club Papers Both incarnations of Tolkien's unfinished time travel story featured a number of pieces in Old English, most accompanied by translations. They can be found in The Lost Road and Other Writings and Sauron Defeated.
- 'Thus cwæth Ælfwine Wídlást...' (Ælfwine's words before departing on his last voyage, included in his preamble to the Silmarillion, and heard in dream by Alboin Errol in The Lost Road and by Edwin Lowdham in The Notion Club Papers) - Lost Road (3 versions) and Sauron Defeated (1 version), one line of prose and five lines of verse, all four versions include a translation.
- 'Hwæt! Éadweard cyning Ælfredes sunu...' (verse prepared by Ælfwine to sing to King Edward) - Sauron Defeated, four lines of verse, with translation. This episode is also prefaced by four lines of Old English dialogue with translation between Ælfwine and the King.
- 'Monað modes lust mid mereflode...' (verse actually sung by Ælfwine for King Edward, similar to The Seafarer. Also heard in dream by Lowdham.) - Lost Road (1 version) and Sauron Defeated (two versions), seven lines of verse, two of the versions include a translation.
- 'Hi alle sǽ on weorulde oferliodon...' (Lowdham's manuscript of the Fall of Numenor) - Sauron Defeated, 36 lines of prose, with translation. Also an earlier 43 line version, with translation, and two related fragments of 15 and 7 lines, only the first of which has a translation.
- 'Hwæt! Wé on geárdagum of Gársecge...' (verse about King Sheave sung by Tréowine)- Sauron Defeated, six lines of verse, not translated
Rohan The language of Rohan is rendered in the books as Old English. Most of this is limited to names and the occasional isolated line of dialogue, but there is one longer segment in an earlier draft published in The Treason of Isengard.
- 'Abídað cuman uncúðe!...' (challenge that the Rohirrim guards give to Aragorn and Legolas when they arrive at Edoras, similar to a passage of Beowulf) - six lines of dialogue with translation

Almost all of these are poems, many of which have only been published in very obscure places.
