Here are some of my favorite novenas:
NOVENA TO THE SACRED HEART
Divine Jesus, Thou hast said, "Ask and you shall receive; seek and you shall find; knock and it shall be opened to you." Behold me kneeling at Thy feet, filled with a lively faith and confidence in the promises dictated by Thy Sacred Heart to Saint Margaret Mary. I come to ask this favor: (Mention your request).
To whom can I turn if not to Thee, Whose Heart is the source of all graces and merits? Where should I seek if not in the treasure which contains all the riches of Thy kindness and mercy? Where should I knock if not at the door through which God gives Himself to us and through which we go to God? I have recourse to Thee, Heart of Jesus. In Thee I find consolation when afflicted, protection when persecuted, strength when burdened with trials, and light in doubt and darkness.
Dear Jesus, I firmly believe that Thou can grant me the grace I implore, even though it should require a miracle. Thou have only to will it and my prayer will be granted. I admit that I am most unworthy of Thy favors, but this is not a reason for me to be discouraged. Thou are the God of mercy, and Thou will not refuse a contrite heart. Cast upon me a look of mercy, I beg of Thee, and Thy kind Heart will find in my miseries and weakness a reason for granting my prayer.
Sacred Heart, whatever may be Thy decision with regard to my request, I will never stop adoring, loving, praising, and serving Thee. My Jesus, be pleased to accept this my act of perfect resignation to the decrees of Thy adorable Heart, which I sincerely desire may be fulfilled in and by me and all Thy creatures forever.
Grant me the grace for which I humbly implore Thee through the Immaculate Heart of Thy most sorrowful Mother. Thou entrusted me to her as her child, and her prayers are all-powerful with Thee. Amen.
NOVENA TO THE BLESSED VIRGIN MARY
O Mary, ever blessed Virgin, Mother of God, Queen of the Angels and of the Saints, I salute thee with the most profound veneration and filial devotion. I renew the consecration of myself and all I have to thee. I thank thee for thy maternal protection and for the many blessings that I have received through thy wondrous mercy and most powerful intercession. In all my necessities I have recourse to thee with unbounded confidence. O Help of Christians, O Mother of Mercy, I beseech thee now to hear my prayer, and to obtain for me of thy Divine Son the favor that I request in this novena. (Here mention your request.)
Obtain for me, also, dearest Mother, the grace that I may imitate thee and become more like to thee in the practice of the virtues of humility, obedience, purity, poverty, submission to the will of God, and charity. Be my protectress in life, guard and guide me in dangers, direct me in perplexities, lead me in the way of perfection, and assist me in the hour of my death, that I may come to Jesus, and with thee enjoy Him, bless Him, and love Him eternally in Heaven. Amen.
(Say the Memorare and the Litany of Our Lady)
NOVENA TO ST. JOSEPH
Saint Joseph, I, your unworthy child, greet you. You are the faithful protector and intercessor of all who love and venerate you. You know that I have special confidence in you and that, after Jesus and Mary, I place all my hope of salvation in you, for you are especially powerful with God and will never abandon your faithful servants. Therefore I humbly invoke you and commend myself, with all who are dear to me and all that belong to me, to your intercession. I beg of you, by your love for Jesus and Mary, not to abandon me during life and to assist me at the hour of my death.
Glorious Saint Joseph, spouse of the Immaculate Virgin, obtain for me a pure, humble, charitable mind, and perfect resignation to the divine Will. Be my guide, my father, and my model through life that I may merit to die as you did in the arms of Jesus and Mary.
Loving Saint Joseph, faithful follower of Jesus Christ, I raise my heart to you to implore your powerful intercession in obtaining from the Divine Heart of Jesus all the graces necessary for my spiritual and temporal welfare, particularly the grace of a happy death, and the special grace I now implore: (Mention your request).
Guardian of the Word Incarnate, I feel confident that your prayers in my behalf will be graciously heard before the throne of God. Amen.
NOVENA TO ST. JUDE
O most holy and glorious apostle, Saint Jude, faithful servant and friend of Jesus, the true Church honors and invokes thee universally, as the patron of hopeless cases, and of things almost despaired of. Pray for me, who am so miserable. Make use, I implore thee, of that particular privilege accorded to thee, to bring visible and speedy help where help was almost despaired of. Come to mine assistance in this great need, that I may receive the consolation and succor of Heaven in all my necessities, tribulations, and sufferings, particularly (-here make your request-) and that I may praise God with thee and all the Elect throughout Eternity. I promise thee, O blessed Jude, to be ever mindful of this great favor, to always honor thee as my special and powerful patron, and to gratefully encourage devotion to thee. Amen.
Saint Jude, Apostle martyr and relative of Our Lord Jesus Christ, Mary and of Joseph, intercede for us.
