מצב שבת (Sabbath Mode או Shabbat Mode באנגלית) הוא מאפיין במכשירים ביתיים מודרניים רבים, לרבות תנורים, מדיחי כלים, ומקררים, שנועד לאפשר למכשירים לשמש (בכפוף לאילוצים שונים) על ידי יהודים שומרי שבת בשבתות ובחגים יהודיים. המצב בדרך כלל עוקף את פעולתו הרגילה והיומיומית של המכשיר החשמלי וגורם להפעלת המכשיר לעמוד בכללי ההלכה.

While according to Halakha, raw food may not be cooked on the Shabbat, food that was already cooked beforehand may be kept warm until mealtime. In the past, the Sabbath-observant would leave their food heating on the stove where it had been covered with a blech (metal sheet), or in the oven in which it had been cooked before the onset of Sabbath. Contemporary consumers seek to use their kitchen's oven to keep food hot for Sabbath consumption but must be assured that in opening the door to retrieve food, no Sabbath laws will be inadvertently contravened. An example of this would be ovens which are programmed to remove power from their heating element when the door is opened – use of this oven would not be possible on the Sabbath without making modifications.

On weekday holidays (Yom Tov), food may be cooked, but turning the heat on is prohibited. On these festive days, the domestic needs of the Sabbath observant consumer may require that their oven be heated over as much as 72 hours to allow for cooking during the festival. In the past, one would simply light a stove or oven before the festival began, and its heat was used over the coming days. In recent decades, however, appliance manufacturers have instituted safety features that present a challenge to festival use. One typical challenge is the auto-shut-off which automatically shuts off the heat after a predetermined number of hours.

For an appliance to be compliant with religious requirements when Shabbat mode is operating, the standard six- or twelve-hour automatic shutoff should be overridden, and all lights and displays (for example, a light that might go on when the door is opened) should be disabled. However, several manufacturers have not dealt with the issues caused by the heating elements and the thermostats, which in some Sabbath modes continue to operate as normal, which is in contradiction to normative halachic opinion. Some models do not even take care of the issue of the lights.

In more recently designed ovens, Shabbat mode will often feature the ability to adjust the temperature of the oven without any feedback to the operator of the oven. תבנית:Cn span

With some Shabbat mode ovens that are controlled using a keypad to set the temperature, there is a random delay triggered after a button is pressed before the temperature change takes place.

In June 2008, nine Haredi poskim signed a public pronouncement (Kol Kore) stating that it was forbidden to raise or lower the temperature by reprogramming on Yom Tov using the Star-K Kosher Certification approved Shabbat Mode feature. The pronouncement referred to the differing opinion of Rabbi Moshe Heinemann (although without explicitly mentioning Rabbi Heinemann by name) as a minority opinion (Da'as Yachid) that should not be relied upon. However, Rabbi Heinemann said that he continued to stand by his opinion that it is permissible.

מקרר מצב שבת כולל, לפחות, את היכולת לנטרל את כל האורות או פעילות חשמלית אחרת בעת פתיחת דלת המקרר. חלק מהמקררים במצב שבת כוללים טיימר למדחס כך שפתיחת הדלת, שבדרך כלל תגרום בעקיפין להפעלת המדחס ברגע שהטמפרטורה תעלה, לא תשפיע מיידית על פעולתו החשמלית של המכשיר.
