Sandis Valters (born 31 August 1978) is a retired professional basketball shooting guard, who last played for BK Ventspils.

For the 2005–06 season Valters had offers from Greece, Israel and Russia,[1] but instead opted for a return to Riga, signing a contract with then up-and-coming team ASK Rīga.

During the season Valters was selected in every tournament's All-Star game (LBL, BBL and FIBA EuroCup) that his club participated in.

In early 2009, Valters left ASK as the club went through financial problems, signing for the remainder of the season with the Italian team from Imola.

An injury during the Eurobasket 2009 preparation game[4] with Latvian national team forced Valters to miss the first half of the 2009–10 season.
