Princess Ulrike Louise of Solms-Braunfels (1 May 1731 in Hungen, Landgraviate of Hesse-Darmstadt – 12 September 1792 in Bad Homburg) was a German regent, Landgravine of Hesse-Homburg by marriage to Frederick IV of Hesse-Homburg, and regent of Hesse-Homburg, on behalf of her minor son Frederick V Louis William Christian from 1751 to 1766.

Ulrike Louise was a daughter of Prince Frederick William of Solms-Braunfels (1696–1761) and his second wife, Countess Sophie Magdalene of Solms-Laubach-Utphe (1701–1744), daughter of Count Otto of Solms-Laubach-Utphe (1673-1743) and Countess Luise Albertine of Schönburg-Waldenburg (1686-1740).

She married on 10 October 1746 in Hungen her cousin, Landgrave Frederick IV of Hesse-Homburg (1724–1751).

The dispute could be arbitrated, and Frederick IV was reinstated as ruling Landgrave.

She managed to preserve the sovereignty of Hesse-Homburg and marry her son to a daughter of Landgrave Louis IX of Hesse-Darmstadt.
