Count Thomas de Savoie, (ca. 1199–1259) was the regent of the County of Savoy when his nephew, Boniface, was fighting abroad. He was also the consort Count of Flanders (1237–1244) and the count of Piedmont (1244–1259). He was the son of Thomas I of Savoy and Marguerite of Geneva. Historians and genealogists have later retrospectively dubbed him as Thomas II of Savoy in order to dstinguish him from other Thomases of the House of Savoy.

He was married two times. First, with Jeanne, Countess of Flanders, who died 1244, Countess of Flanders and Hainaut, daughter of Baldwin I of Constantinople. This marriage was childless. Second, he married Beatrice di Fieschi, niece of Pope Innocent IV and had 6 children:

1. Thomas of Piedmont (1248–16 May 1282), pretender of Count of Savoy, married in 1274 to Guia of Burgundy, the step-daughter of Philip I of Savoy and had 5 children:
   1. Philip, first of the line of Savoy-Achaea, lasting from 1285 to 1418
   2. Peter
   3. Thomas
   4. Amadeus
   5. William
2. Amadeus V of Savoy (1249, Bourget-du-Lac–16 October 1323, Avignon). He founded the line of Counts of Savoy which continues to modern days and until 1418, was genealogically a cadet branch of this House.
3. Louis, Baron de Vaud (1250 – after 10 January 1302), Baron de Vaud, married
   1. Adeline of Lorraine (d. a. 1278), daughter of Matthias II, Duke of Lorraine,
   2. in 1278: Jeanne of Montfort (d. 1300), daughter of Philip of Montfort, Lord of Castres,
   3. May 1, 1301: Isabelle d'Aulnay (d. October 30, 1341)
4. Eleonora (d. 6 December 1296), married 1270 Louis I de Beaujeu.
5. Margaret (d. May 1292), married
   1. 1257: Baldwin de Reviers, 7th Earl of Devon, d. 1262
   2. 1269: Sir Robert Aguillon d. 15 February 1286
6. Alice (d. 1 August 1277).

He also had at least 3 illegitimate children.

Although he was the next brother of Amadeus IV, he never became the Count of Savoy because he predeceased his nephew count Boniface who himself died without sons to succeed. Although Thomas left sons, uktimately to continue the dynasty of Savoy, upon Boniface's death the remaining uncles, younger brothers of Thomas, succeeded as Counts of Savoy. Thomas' eldest son and heir Thomas III felt that be an injustice, and claimed unsuccessfully Savoy from his uncles. However, it so happened that Philip, the last surviving brother of Thomas, made Thomas' younger son Amadeus as hios heir in County of Savoy, leaving the elder son, Thomas, and the genealogically senior line decending from him out from the Savoy succession.
